Vitamin D supplementation reduces risk of maternal comorbidities and helps improve neonatal outcomes.

The human peripheral leukocyte subset composition depends on genotype variation and pre-natal and post-natal environmental influence diversity. We quantified this composition in adults and neonates, and compared the median values and dispersal ranges of various subsets in them. We confirmed higher frequencies of monocytes and regulatory T cells (Tregs), similar frequencies of neutrophils, and lower frequencies of CD8 T cells, NKT cells, B1 B cells and gamma-delta T cells in neonatal umbilical cord blood. Unlike previous reports, we found higher frequencies of eosinophils and B cells, higher CD4:CD8 ratios, lower frequencies of T cells and iNKT cells, and similar frequencies of CD4 T cells and NK cells in neonates. We characterized monocyte subsets and dendritic cell (DC) subsets in far greater detail than previously reported, using recently described surface markers and gating strategies and observed that neonates had lower frequencies of patrolling monocytes and lower myeloid dendritic cell (mDC):plasmacytoid DC (pDC) ratios. Our data contribute to South Asian reference values for these parameters. We found that dispersal ranges differ between different leukocyte subsets, suggesting differential determination of variation. Further, some subsets were more dispersed in adults than in neonates suggesting influences of postnatal sources of variation, while some show the opposite pattern suggesting influences of developmental process variation. Together, these data and analyses provide interesting biological possibilities for future exploration.

INTRODUCTIONMenstrual irregularities affect 2-5% of childbearing women, a number that is considerably higher among females under constant stress during a cycle [1]. A woman's menstrual cycle typically follows a 28-day cycle and ends with the shedding of uterine lining leading to bleeding. The normal menstrual cycle indicates the proper functioning of hormones, having a normal menstrual cycle signifies a healthy hypothalamo-pitutary axis with a normal uterus. However, a number of conditions such sudden weight loss, over-exercising, medical conditions and even stress can interfere with a woman's ability to experience a normal menstrual cycle. Both longer duration of menstrual bleeding and cycle irregularity are associated with major depression.Although there appears to be a relationship between the type and severity of the stress and the proportion of women who develop menstrual problems, in practice it is difficult if not impossible to identify a threshold at which stress will interfere with the normal cycle. The individual response to abnormality in body function is heightened due to psychobiological characteristics [2][3]. This study was planned to establish a correlation between the levels of perceived stress and its effect on the menstrual cycle. MATERIALS AND METHODSThis cross-sectional study was conducted in the undergraduate girl's hostel of a medical college. Hundred female students aged above 18 years were the target population of the study. The students with current medical, psychiatric or gynaecological problems like pregnancy and amenorrhea were excluded from the study.The participants were given liberal verbal explanations plus description letters about the topic and the aim of the study with attached consent forms. After the students had duly signed the consent form, a questionnaire along with the PSS (available freely online) [4] and PBAC (prior permission taken) [5] was provided to them.The questionnaire dealt with anthropometric data, lifestyle, menstrual history, and menstrual health status. Body Mass Index (BMI) was calculated using self-reported data on height and weight. The students were then asked to record their menstrual pattern on the PBAC for the next menstrual cycle and fill the PSS for the month. Based on the answers, PSS was calculated for each participant.The PSS is the most widely used psychological instrument for measuring the perception of stress [4]. It is a measure of the degree to which situations in one's life are appraised as stressful. Items were designed to tap how unpredictable, uncontrollable, and overloaded respondents find their lives. The scale also includes a number of direct queries about current levels of experienced stress. The questions in the PSS ask about feelings and thoughts during the last month. In each case, respondents are asked how often they felt a certain way. 5, 7, & 8) and then summing across all scale items. The subjects who scored ≤20 on the PSS were categorized to have low stress levels, while subjects with score >20 were categorized to have hig...

Smile is one of the most natural and important expressions of human emotion. Man uses his lips mainly to register his emotions. Thus, the slightest asymmetry or weakness around the lips and mouth may transform this pleasant expression into embarrassment and distortion. The circumoral musculature, the major part of which is supplied by the marginal mandibular branch of the facial nerve, is the main factor in this expression. Therefore, an injury to this nerve during a surgical procedure can distort the expression of the smile as well as other facial expressions. This nerve often gets injured by surgeons in operative procedures in the submandibular region, like excision of the submandibular gland due to lack of accurate knowledge of variations in the course, branches and relations. In the present study, 50 facial halves were dissected to study the origin, entire course, termination, branches, muscles supplied by it, its anastomoses with other branches of facial nerve on the same as well as on the opposite side and its relations with the surrounding structures. The marginal mandibular branch of the facial nerve was found superficial to the facial artery and (anterior) facial vein in all the cases (100%). Thus the facial artery can be used as an important landmark in locating the marginal mandibular nerve during surgical procedures. Such a study can help in planning precise and accurate incisions and in preventing the unrecognized severance of this nerve during surgical procedures.

Ovarian cancer is one of the neoplasms affecting the reproductive tract associated with high mortality rate because of limited therapeutic options and an elevated incidence of chemoresistance and recurrence. In this context, immunotherapy may constitute a promising approach to improve survival rates and clinical outcome, raising the need for specific target antigens. Cancer-testis antigens (CTAs) are considered promising candidates in this sense because they are aberrant expressed by various malignancies but not by non-transformed tissue, with the exception of testes. Here, we examined the expression and potential to promote humoral immune responses of a novel CTA, A-kinase anchor protein 4 (AKAP4), among 38 ovarian carcinoma patients. Our results reveal that AKAP4 was expressed at both the mRNA and protein levels in 89% (34/38) of ovarian carcinoma tissue specimens but not in 21 matched adjacent non-cancerous tissues. In addition, a humoral response against AKAP4 was detected in 58% (22/38) of ovarian carcinoma patients by ELISA. In particular, 65% (22/34) patients bearing an AKAP4-expressing tumor exhibited circulating anti-AKAP4 antibodies. Interestingly, the majority of specimens were categorized as ovarian serous adenocarcinoma and serous papillary carcinoma, of which 93% (28/30) and 100% (6/6), respectively, expressed AKAP4. A humoral response against AKAP4 was detected in 79% (19/24) and 67% (4/6) of ovarian serous adenocarcinoma and serous papillary carcinoma patients, respectively. The presence of circulating anti-AKAP4 antibodies suggests the AKAP4 is highly immunogenic in ovarian serous carcinoma patients. Our study lays the foundations for exploring AKAP4 as a potential target for the immunotherapy of ovarian cancer.

The present study shows that the GT allele of VDBP SNP rs7041, the VDBP allelic combination (GC1F/1F), and GA allele of CYP2R1 SNP rs2060793 in vitamin D deficient women increase the risk of PCOS.
