Background: Various ginger compounds improve gastrointestinal problems and motion sickness. The main effects of ginger allocate to some phenolics such as gingerols and shogaols that act as their active agents. Chewing gums are among convenient dosage forms which patients prefer due to their advantages. Hence, this study tried to design, formulate, and evaluate ginger chewing gum of favorable taste and texture to avoid motion sickness and have gastro-protective and anti-oxidant effect. Materials and Methods: Dried ginger rhizomes were percolated to extract ginger compounds. Total phenolics were measured in 70% hydro-alcoholic extract of ginger by gallic and tannic acid standards using Folin–Ciocalteu's reagent. Chewing gums containing 50 mg of concentrated extract were prepared. Content uniformity, weight variation, release pattern, organoleptic, and mechanical properties were evaluated. Results: Phenolic content was measured 61.50 ± 5.27 mg/g and 76.75 ± 5.45 mg/g of concentrated extract as gallic acid and tannic acid equivalents, respectively. Release pattern of formulations with different gum bases and sweeteners demonstrated almost 100% release of drug. Evaluation of organoleptic properties was on 10 healthy volunteers and later prepared formulations exhibited better characteristics. Formulations without any flavorants have higher acceptability. Evaluation of mechanical properties showed higher stiffness of F₁₅. Conclusion: Ginger chewing gum comprises admissible properties to be used as a modern drug delivery system due to its advantageous results in motion sickness. It passed all the specified tests for an acceptable chewing gum. Thus, it may be successfully produced to help GI problems.

Background: Breast cancer is the second leading cause of deaths from cancer in the woman. MicroRNAs (miRNAs) are endogenous noncoding RNAs that are known critical player in carcinogenesis. The role of miR-370 in malignancies remains controversial because of its levels varying in different cancers according to its targets while the role of miR-370 in breast cancer has not been addressed so far. The aim of this study was to identify the expression pattern of miR-370 in human breast cancer tissue compared to adjacent healthy tissue. Materials and Methods: Twenty-two fresh frozen tissues (normal and malignant) from patients with breast cancer were examined for miR-370 by quantitative real-time polymerase chain reaction method at 2013. Results: We observed up-regulation (six-fold higher) of miR-370 in breast cancer tissue compared with normal adjacent tissue. Tumor samples in stage III, invasive ductal type, larger tumor size, human epidermal growth-factor receptor 2+, estrogen receptor/progesterone receptor−, P53 − status showed significantly increased expression in miR-370. Conclusion: Together, miR-370 may acts as an onco-miRNA, and it may have a novel role in breast cancer. Detection of miR-370 and its targets could be helpful as a diagnostic biomarker and therapeutic target.

Background: The recent focus is on the increase in the burden of falciparum cases with a varied spectrum of presentation and outcome, especially in developing countries like India. This study was undertaken to analyze the trend and manifestations of falciparum malaria in a tertiary care hospital. Materials and Methods: This descriptive study was carried out at the Gauhati Government Medical College and Hospital from June 2006 to May 2007. The data were collected on demographic and time characteristics, clinical and laboratory findings, the outcome of disease and expressed in proportion or percentages. Results: Out of the 100 cases, around 2^nd/3^rd (63%) of cases were in the age group of 15–30 years and the mean age was found to be 29.51 years. About 66% of them were males. Clinical presentations included pain abdomen (42, 42%), nausea and vomiting (35, 35%), jaundice (34, 34%), oliguria (24, 24%), altered sensorium (24, 24%), breathing difficulty (10, 10%), and seizures (5, 5%). Number of cases and mortality were more with a peak in the month of May and September. Manifestations of severe falciparum malaria included hepatopathy (38%), renal failure (28%), shock (9%), acute respiratory distress syndrome (7%), hypoglycemia (3%), and severe anemia (1%). Eighty-two cases (82%) recovered and 18 cases (18%) expired. Conclusion: Falciparum malaria is more among younger adult age group and males. Complications and mortality are also more due to falciparum malaria.

Background: Tumor development is angiogenesis dependent. There is evidence that leptin contributes to tumor growth. However, all the mechanisms by which leptin does this has not been clearly established. The objective of the present study was to test the hypothesis that leptin enhances melanoma tumor growth through inducing angiogenesis and cell proliferation. Materials and Methods: We injected 2 × 10⁶ B16F10 melanoma cells subcutaneously to 32 C57BL6 mice. The mice were randomly divided into four groups of eight animals, on day 8. Two groups received twice daily intraperitoneal (i.p.) injections of either phosphate buffered saline or recombinant murine leptin (1 μg/g initial body weight). Two groups received i.p. injections of either 9F8 an anti leptin receptor antibody or the control mouse IgG at 50 μg/injection every 3 consecutive days. By the end of the 2^nd week, the animals were euthanized and blood samples and tumors were analyzed. Angiogenesis and proliferation were assessed by immunohistochemical staining for CD31 and Ki-67 respectively. Results: Tumors size, capillary density, plasma levels of vascular endothelial growth factor, and the number of Ki-67-positive stained cells were significantly more in the leptin than 9F8 and both control groups (P < 0.05). Conclusion: Taken together, our findings reinforce the idea that leptin acts as an angiogenic and mitogenic factor to promote melanoma growth.

Background: Leishmaniasis is a major health problem in some endemic areas of tropical and subtropical areas of the world. Interleukin-12 (IL-12) and interferon gamma (IFN-γ) are essential cytokines associated with initiation of Th1 response. The main objective of this study was to evaluate of the type of immune response to L. major isolates from patients with no clinical response to antimonite (Glucantime). Materials and Methods: This experimental study was carried out during 2013–2014. In the current study Leishmania major were isolated from 10 CL patients with a history of at least one course of treatment with Meglumine antimonate (Sb5). The isolates were used to evaluatein vitro andin vivo response to Sb5. J774 murine macrophage cell line was used forin vitro tests and Balb/c mice was used forin vivo studies. IL-12 gene expression was evaluated using Real-time PCR and IFN-γ serum level was quantified using ELISA technique. SPSS (version: 20), analysis of Covariance (ANCOVA) was used for statistical analysis. Results: PCR results confirmed that all 10 isolates were L. major. The mean of IL-12 gene expression in vitro,in vivo and IFN-γ serum levels (pg/ml) after 2 and 3 weeks treatment in vivo, increased significantly following the treatment with Glucantime in the two groups of Balb/c mice infected either with patients' isolates or standard L. major. No significant difference was seen between the patients' isolates and standard species. Conclusions: Although the L. major were isolated from patients with active lesion and no clinical response to Glucantime after at least one courses of Glucantime treatment butin vivo andin vitro immune response of L. major isolates showed no difference between the patients' isolates and standard L. major.

Background: Post inflammatory hyperpigmentation (PIH) is a common problem occurs following many dermatologic diseases and medical interventions. Different modalities including topical agents, lasers and intense pulsed light (IPL) are suggested for treatment of the post-burn PIH. In the current study, we evaluated the efficacy of IPL plus modified Kligman cream (MODIFIED KLIGMAN CREAM) versus MODIFIED KLIGMAN CREAM alone in the treatment of the post-burn PIH. Materials and Methods: This was a randomized, non-blinded clinical trial. A total of 53 patches of post-burn PIP in 14 patients were randomized to receive either two sessions of IPL plus modified Kligman formula or kligman formula for 2 months. The patients were recommended to apply MODIFIED KLIGMAN CREAM cream for 12 h at night. Results: According to our results, the patients in the MODIFIED KLIGMAN CREAM + IPL group had higher satisfaction as compared with MODIFIED KLIGMAN CREAM alone (P = 0.000) (Mann–Whitney test). In addition, according to physician evaluation, the patients in the MODIFIED KLIGMAN CREAM + IPL group had higher satisfaction as compared with MODIFIED KLIGMAN CREAM alone (P = 0.000) (Mann–Whitney test). No side effects except a little irritation, erythema and exfoliation due to MODIFIED KLIGMAN CREAM cream were seen in the patients. Conclusions: The results of our study showed the better efficacy and faster response of the IPL plus modified Kligman formula versus modified Kligman formula in the treatment of the post-burn PIH. To better determine the efficacy of IPL in treatment of the post-burn PIP, more extensive studies as randomized, double-blinded clinical trial are recommended.

Background: One of the most common causes of hospital-acquired secondary infections in hospitalized patients is Pseudomonas aeruginosa. The aim of this study is to evaluate the expression of IMP and VIM in Pseudomonas aeruginosa strains (carbapenem resistant and producer MBL enzyme) in patients with secondary immunodeficiency. Materials and Methods: In a cross sectional study, 96 patients with secondary immunodeficiency hospitalized in the Al-Zahra hospital were selected. Carbapenem resistant strains isolated and modified Hodge test was performed in order to confirm the presence of the metallo carbapenemase enzyme. Under the standard conditions they were sent to the central laboratory for investigating nosocomial infection Multiplex PCR. Results: Of 96 samples 28.1% were IMP positive, 5.2% VIM positive and 3.1% both VIM and IMP positive. The prevalence of multidrug resistance in the IMP and/or VIM negative samples was 29%, while all 5 VIM positive samples have had multidrug resistance. Also the prevalence of multi-drug resistance in IMP positive samples were 96.3% and in IMP and VIM positive samples were 100%. According to Fisher's test, the prevalence of multi-drug resistance based on gene expression has significant difference (P < 0.001). Conclusion: Based on the results of this study it can be concluded that, a significant percentage of patients with secondary immunodeficiency that suffer nosocomial infections with multidrug resistance, especially Pseudomonas aeruginosa, are probably MBL-producing gene positive. Therefore the cause of infection should be considered in the hospital care system to identify their features, the presence of genes involved in the development of multi-drug resistance and antibiotic therapy.

Background: Regarding the anti-oxidative effects on the central nervous system, the possible protection against brain tissues oxidative damage as a possible mechanism for improving effects of low doses of estradiol on scopolamine-induced learning and memory impairments was investigated in ovariectomized (OVX) rats. Materials and Methods: The OVX rats treated by (1) vehicle, (2) scopolamine, and (3–4) scopolamine plus estradiol (20 or 20 or 60 μg/kg). Estradiol was administered (20 or 60 μg/kg, intraperitoneally) daily for 6 weeks after ovariectomy. The rats were examined for learning and memory using passive avoidance test. Scopolamine (2 mg/kg) was injected 30 min after training in the test. The brains were then removed to determine malondialdehyde (MDA) and thiol contents. Results: Scopolamine shortened the time latency to enter the dark compartment in (P < 0.01). Compared to scopolamine, pretreatment by both doses of estradiol prolonged the latency to enter the dark compartment (P < 0.01). The brain tissues MDA concentration as an index of lipid peroxidation was decreased (P < 0.05). Pretreatment by estradiol lowered the concentration of MDA, while it increased thiol content compared to scopolamine (P < 0.05 andP < 0.01). Conclusions: These results allow us to suggest a protection against brain tissues oxidative damage as a possible mechanism for improving effects of low doses of estradiol on scopolamine-induced learning and memory impairments in OVX rats.

Background: Liver biopsy is required to diagnose non-alcoholic steatohepatitis in patients with suspected non-alcoholic fatty liver disease (NAFLD). This study aimed to examine the relationship between sonographic diagnosis of fatty liver with histopathologic abnormalities and liver biopsy findings in patient with NAFLD. Materials and Methods: In this cross-sectional study, a total of 180 patients, with an age range of 18-60 year old, with NAFLD based on ultrasonograghic findings were evaluated. Age, sex, body mass index, diabetes mellitus, hypertension, family history of liver disease and laboratory parameters recorded for all patients. Hence, grade of steatosis and stage of fibrosis were evaluated by liver biopsy. Results: A total of 220 patients were enrolled. Liver biopsy was performed in 180 patients. Mean age was 43 ± 10.6 years old and 66% were male. Ultrasonograghic findings showed mild, moderate and severe NAFLD was define in 100 (55.5%), 72 (40%) and 8 (4.5%) of patients, respectively. Liver biopsies showed that steatosis scores of <5%, 5-33% and 33-66% was define in 56 (31%), 116 (64%) and 9 (5%) of patients, respectively. Furthermore, fibrosis was defined as follow; none 92 (51%), mild 68 (38%), moderate 11 (6%), bridging 5 (3%) and cirrhosis 3 (2%) patients. There was no statistically significant relationship between ultrasonograghic findings and steatosis scores (P = 0.44), but statistically significant relationship was found between ultrasonograghic findings and fibrosis stage (P = 0.017). Conclusion: Findings revealed that, in patients with NAFLD, ultrasonographic finding were not in associate to steatosis, but were in relation with fibrosis stage.

Background: This study was designed to compare the efficacy of the medical treatment versus the surgical treatment approach to decompression of trigger point nerves in patients with migraine headaches. Materials and Methods: Fifty volunteers were randomly assigned to the medical treatment group (n = 25) or the surgical treatment group (n = 25) after examination by the team neurologist to ensure a diagnosis of migraine headache. All patients received botulinum toxin type A to confirm the trigger sites. The surgical treatment group underwent surgical deactivation of the trigger site(s). The medical treatment group underwent prophylactic pharmacologic interventions by the neurologist. Pretreatment and 12-month posttreatment migraine headache frequency, duration, and intensity were analyzed and compared to determine the success of the treatments. Results: Nineteen of the 25 patients (76%) in the surgical treatment group and 10 of the 25 patients (40%) in the medical treatment group experienced a successful outcome (at least a 50% decrease in migraine frequency, duration, or intensity) after 1 year from surgery. Surgical treatment had a significantly higher success rate than medical treatment (P < 0.001). Nine patients (36%) in the surgical treatment group and one patient (4%) in the medical treatment group experienced cessation of migraine headaches. The elimination rate was significantly higher in the surgical treatment group than in the medical treatment group (P < 0.001). Conclusions: Based on the 1-year follow-up data, there is strong evidence that surgical manipulation of one or more migraine trigger sites can successfully eliminate or reduce the frequency, duration, and intensity of migraine headaches in a lasting manner.

Background: The carpal tunnel syndrome (CTS) is the most common neuropathy. The aim of this study was to evaluate the effect of a new and noninvasive treatment including extracorporeal shock wave therapy (ESWT) in the treatment of CTS. Materials and Methods: This study is a clinical trial conducted on 60 patients with moderate CTS in selected health centers of Isfahan Medical University from November 2014 to April 2015. Patients with CTS were randomly divided into two groups. Conservative treatment including wrist splint at night for 3 months, consumption of nonsteroidal anti-inflammatory drugs for 2 weeks, and oral consumption of Vitamin B1 for a month was recommended for both groups. The first group was treated with ESWT, one session per week for 4 weeks. Focus probe with 0.05, 0.07, 0.1, and 0.15 energy and shock numbers 800, 900, 1000, and 1100 were used from the first session to the fourth, respectively. The evaluated parameters were assessed before treatment and after 3 and 6 months. Data were analyzed using SPSS version 19, Student's t-test, and Chi-square test. Results: All parameters were significantly decreased in the ESWT group after 3 months. These results remained almost constant after 6 months compared with 3 months after treatment. However, only two parameters considerably improved after 3 months of treatment in the control group. The entire indexes in the control group implicated the regression of results in long-term period. Conclusion: It is recommended to use ESWT as a conservative treatment in patients with CTS.

Background: Preeclampsia is a multisystem disorder of unknown etiology that affects 4–5% of all pregnancies. The aim of the study was to evaluate the diagnostic accuracy of serum soluble endoglin (sEng) in preeclampsia and eclampsia and also to evaluate its prognostic significance. Materials and Methods: This prospective case–control study carried out over a period of 1 year in the Department of Obstetrics and Gynaecology, King George Medical University, Lucknow. After written informed consent and ethical clearance, total 90 subjects were enrolled. Among them, 30 subjects of eclampsia, 15 of nonsevere preeclampsia, 15 of severe preeclampsia served as cases, and 30 healthy pregnant normotensive women served as controls. Levels were estimated by enzyme-linked immunosorbent assay technique in both cases and controls. Results: Mean level was highest in eclampsia group (14.96 ± 1.96 ng/mL) and lowest in controls (2.08 ± 0.56 ng/mL). At cut-off value of sEng levels of ≥6.26 ng/mL, it was found to be 100% sensitive and 100% specific for the diagnosis of preeclampsia (area under curve =1) at 95% confidence interval. sEng levels were strongly correlated with systolic (r = 0.928) and diastolic blood pressure (r = 0.916), serum lactate dehydrogenase (r = 0.791) and serum uric acid (r = 0.722). All four maternal deaths were reported within eclampsia group, in whom the mean sEng level was significantly higher (17.84 ± 0.22) as compared to other subjects (9.50 ± 5.80). Conclusion: sEng is a novel marker for diagnosis of preeclampsia, and it can also be used as a prognostic marker to predict the severity of preeclampsia.

Background: Hypercoagulable state is a common serious problem in patients with end-stage renal disease (ESRD). ESRD patients are in a condition of chronic inflammation. An increased level of E-selectin, “a key adhesion molecule that regulates leukocyte bindings to endothelium at damaged sites,” accompanies the higher risk of inflammation in ESRD patients. We aimed to investigate the possible correlation among E-selectin as an adhesion molecule, coagulation factors, and inflammatory factors in children with ESRD. Materials and Methods: Thirty-five child patients with ESRD who had been on regular dialysis treatment were registered in our study. Nighteen sex- and age-matched healthy volunteers were used as the control group. Laboratory tests were requested for the evaluation of hematological and biochemical parameters, and parathyroid hormone (PTH), and for coagulation state; fibrinogen, protein C, and protein S were measured. The enzyme-linked immunosorbent assay (ELISA) (Biomerica, CA, and IDS, UK). for serum E-selectin assay was provided by R and D Systems (Abingdon, UK). Results: Hemoglubolin (Hb), blood urea nitrogen (BUN), creatinine, calcium, PTH, triglyceride (TG) concentrations in serum as well as E-selectin showed significant difference between the two study groups, as indeed was expected. Serum E-selectin was significantly higher (P value = 0.033) in dialysis patients than in healthy subjects. E-selectin was positively correlated only with phosphorus in ESRD children (r = 0.398,P = 0.018). No association was found for other parameters. Conclusion: Although in our study circulating E-selectin concentration “as an inflammatory maker” is independently positively associated with limited blood markers, for better evaluation, well-designed cohort studies should be examined in ESRD children.

Background: Cryopreservation is basically related to meritorious thin samples or small clumps of cells that are cooled quickly without loss. Our main objective is to establish and formulate an innovative method and protocol development for cryopreservation as a gold standard for clinical uses in laboratory practice and treatment. The knowledge regarding usefulness of cryopreservation in clinical practice is essential to carry forward the clinical practice and research. Materials and Methods: We are trying to compare different methods of cryopreservation (in two dozen of cells) at the same time we compare the embryo and oocyte freezing interms of fertilization rate according to the International standard protocol. Results: The combination of cryoprotectants and regimes of rapid cooling and rinsing during warming often allows successful cryopreservation of biological materials, particularly cell suspensions or thin tissue samples. Examples include semen, blood, tissue samples like tumors, histological cross-sections, human eggs and human embryos. Although presently many studies have reported that the children born from frozen embryos or "frosties, "show consistently positive results with no increase in birth defects or development abnormalities is quite good enough and similar to our study (50-85%). Conclusions: We ensure that cryopreservation technology provided useful cell survivability, tissue and organ preservation in a proper way. Although it varies according to different laboratory conditions, it is certainly beneficial for patient's treatment and research. Further studies are needed for standardization and development of new protocol.

Background: The use of herbals in the treatment of diabetes mellitus is a well-established practice in traditional medicine. The medicinal plant Prosopis farcta has some antioxidant activity, which may be useful in diabetic patients. Since, there is no report on the antidiabetic effect of the P. farcta, this study evaluated antidiabetic activity of P. farcta bean extract (PFE) in streptozotocin (STZ)-induced diabetic rats. Materials and Methods: Hyperglycemia was induced in male albino Wistar rats by intraperitoneal injection of STZ (55 mg/kg body weight [BW]), after which, the animals were randomly allocated into six experimental groups as follows: Group 1: Normal rats (received normal saline), Groups 2 and 3: Normal rats received PFE; (50 and 75 mg/kg BW), Group 4: Diabetic control rats, Group 5: Diabetic rats received PFE (50 mg/kg BW), Group 6: Diabetic rats received PFE (75 mg/kg BW). Three days after induction of diabetes, rats were received an extract of PFE orally for 12 days. Blood samples were collected by cardiac puncture to determine liver enzymes; aspartate aminotransferase and alanine aminotransferase (AST and ALT), cholesterol, triglyceride (TG), high and low density lipoproteins (HDL and LDL). Results: The administration of PFE (50 and 75 mg/kg) in STZ-induced diabetic rats significantly reduced the blood glucose levels when compared with the STZ-control group (227.2 ± 12.00 and 259.6 ± 7.03 vs. 454.6 ± 12.66, P < 0.001). PFE in diabetic groups had no significant effect on the levels of cholesterol, TG, HDL, LDL, AST, and ALT compare to the STZ-control group. Conclusion: P. farcta could reduce blood glucose in diabetic rats.

Recently prevention strategies for breast cancer are focused on lifestyle modification such as diet. Some dietary factors such as Conjugated linoleic acid (CLA) can lower the risk of breast cancer, metastasis and some factors concerning this malignancy. Many studies have been established in this field, but their results are inconsistent. Therefore, we evaluated this association based on systematic review among published scientific literature. We performed an electronic search using PubMed, Cochrane, Scopus, Google Scholar and Persian database (Iran Medex, magiran) to identify relevant studies. We summarized the findings of 8 papers in this review. Although, three cohort studies were not overall identified a protective effect of CLA dietary intake or CLA content in breast tissue on breast cancer incidence, metastasis and death, one of them showed an inverse association after adjusting for age. Also, among case-control studies a weak inverse association between breast cancer risk and CLA dietary intake and serum levels among post-menopausal women was reported. Besides, a clinical trial showed that some indicator of breast tumor decreased after CLA administration among women with breast adenocarcinoma. Lacking published evidence suggested inconsistent results. So, further well-designed studies are required, particularly in considering the main breast cancer risk factors.
