Cytokine Storm in Hypothyroidism in Infertile Women

Thyroid dysfunction interferes with several aspects of reproduction along with pregnancy. Hypothyroidism in females leads to an elevated level of hormone prolactin which decreases levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and finally causes infertility. Obesity acts upon the reproductive cycle by decreasing oestrogen metabolism stimulating menstrual disturbance along with an ovulation. But till date, one of the most underestimated obstacles in fertility is inflammation. Hypothyroidism leads to inflammation in secondary epithelial cells of thyroid gland. This affects immune, nervous system and endocrinal functions of body. Inflammation contributes to oestrogen dominance, a hormonal state that consists of having too little progesterone in the body compared to oestrogen. This leads to progesterone resistance, prevention of progesterone hormone receptors from working properly. This condition also leads to infertility in hypothyroid females. Therefore, not only hormonal profile is sufficient to check up for reproductive problems in the female, but also inflammatory markers like IL-6 and CRP should be added to this profile

Fabrication and characterization of sol-gel-based coatings on quartz glass to obtain antireflective effect at 1054 nm for optics of high power Nd:phosphate glass laser

In order to obtain higher laser-induced damage threshold (LIDT) and lower loss of laser radiation, the incident radiation must have an insignificant absorbance and high anti-reflectance. In this work, a single-layer porous SiO2-based anti-reflective (AR) coating for the optics of Nd:phosphate laser system has been developed on quartz glass optics adopting sol-gel dip coating technique, following quarter wavelength optical design. As measured by spectroscopic ellipsometer, the refractive index (RI) of the coated layer is found to be similar to 1.2. A maximum transmittance of similar to 99% in single-layer-coated quartz glass has been achieved at 1054 nm. In addition, the non-quarter wavelength-based double layer with an optical design (glass/ 0.7153 M / 1.134 L / air) and triple-layer AR coating with an optical design (glass / 0.28 H / 1.65 M / 1.03 L / air, where H, M and L indicate one-quarter wave thick layers of high, medium and low RI materials) have been fabricated. The deposition of M and H layers has been made from mixed metal oxide precursor sols of zirconia-silica, while L has been made from silica precursor sol to obtain porous silica coating. A maximum transmittance of about 98.1 and 97.6% was found at 1054 nm in double- and triple-layer AR-coated samples, respectively. The LIDT values have been measured on the AR coatings. Based upon the number of layers in the AR coatings, the LIDT values varied in the range of 8.7-2.4 J cm(-2) starting from single to double to triple layer. The AR coatings developed by sol-gel dip coating technique could find application in Nd:phosphate high power laser system

Design of Double Barrier Ceramic Radio Frequency Vacuum Window

Vacuum windows are an essential part of any radio frequency (RF) system which launches/couples RF power from an atmospheric to a vacuum environment. This paper describes the RF design of a double barrier ceramic coaxial vacuum window. Alumina 99.5% pure is considered as ceramic barrier material while inner and outer conductors are oxygen-free copper. As the initial design approach the thickness, slope, depth of ceramic in the conductor is varied and the performance of the window is studied. The design is optimised to achieve the best insertion loss, return loss response for operating frequency range up to 65MHz

Characterization of fragment emission in ^{20}Ne (7 - 10 MeV/nucleon) + ^{12}C reactions

The inclusive energy distributions of the complex fragments (3 $\leq$ Z $\leq$ 7) emitted from the bombardment of ^{12}C by ^{20}Ne beams with incident energies between 145 and 200 MeV have been measured in the angular range 10$^{o} \leq \theta_{lab} \leq$ 50^{o}. Damped fragment yields in all the cases have been found to be the characteristic of emission from fully energy equilibrated composites. The binary fragment yields are compared with the standard statistical model predictions. Enhanced yields of entrance channel fragments (5 $\leq$ Z $\leq$ 7) indicate the survival of orbiting-like process in ^{20}Ne + ^{12}C system at these energies.Comment: 18 pages, 13 figure

Co-Creation of Breast Cancer Risk Communication Tools and an Assessment of Risk Factor Awareness: A Qualitative Study of Patients and the Public in India

The incidence of breast cancer (BC) is increasing worldwide, and India reported 179,790 cases in 2020. It is important to inform people of risk factors and methods for risk management through interactive risk communication techniques. Affordable, easy-to-understand transmedia tools for the communication of BC risk were co-created by a multidisciplinary team of doctors, clinical researchers, epidemiologists, health economists, digital designers, and public representatives. Qualitative in-depth interviews were conducted in regional languages to assess the views of patients, relatives, the public, and health professionals in India of these prototypes. There was low awareness of BC, with some understanding of age and hereditary risk factors but limited knowledge of reproductive factors amongst the general public, patients, and relatives. Participants favored storytelling techniques (animation and comic strips/infographics) to explain complex issues such as genetic risk and testing. Co-created BC risk communication transmedia tools should be used to support informed decision making

Utilization of passenger transport subsidy in Kolkata: A case study of Calcutta State Transport Corporation

The present study tries to see whether the subsidy given to CSTC, which is the oldest and the largest state transport corporation operating in and around Kolkata, is really being used to cover the losses they make over the years or to merely cover-up an inefficient performance. The state owned buses are required to serve, not only non-profitable routes in off-peak hours, but also to give social security or employment to a large section of society. The burden of carrying a huge staff structure and serving at an administered and less than competitive price for welfare reasons, makes CSTC liable to an operating loss. Therefore, it makes a case for subsidy. However, the regular commuters experience regarding the condition of and the services provided by these raises a question about the justification of subsidy. In the study it is seen that the subsidy given is not based on any of the components on which it should, economically

Mental health, protective factors and violence among male adolescents: A comparison between urban and rural school students in West Bengal

A cross-sectional study was conducted among 199 (104 urban, 95 rural) male students of classes VIII and IX, of two schools, in urban and rural areas of West Bengal to compare the prevalence of protective factors, mental health issues, and violence among the urban and rural adolescents using a self-administered questionnaire. Higher proportion of urban students than rural (67.3% vs. 62.5%) reported that their guardians understood their problems. Mental health issues like loneliness (17.3% vs. 9.8%), worry (17.3% vs. 10.7%), and suicidal thoughts (19.2% vs. 14.1%) were higher among urban students. Physical fight (53.8% vs. 11.6%), bullying (46.4% vs. 17%), physical attack by family members (46% vs. 17%), and by teachers (53% vs. 10.7%) were all more in urban adolescents. Mental health- and violence-related issues were prevalent more among urban students than those among rural students in spite of having more protective factors suggesting the need of frequent supervision, monitoring, and support of adolescents

Identity and Learning: a study on the effect of student-teacher gender matching on learning outcomes

In this paper we examine whether students' and teachers' identity play any role in the learning outcome of students. Specifically, we ask if a student benefits by learning from a teacher of her same gender. Unlike the existing literature which explains such interaction through role model effect or Pygmalion effect, we explain such interaction in terms of gender based sorting behaviour across private and public schools. Our results are driven by two critical differences between male and female individuals. For male and female teachers, the difference comes from their differential transaction costs of traveling to schools at remote locations. For students, the difference between male and female members comes from the differential returns to education accrued to their parents; for girl students, a lower fraction of the return comes to their parental families as they start living with their husband's family after their marriages. These factors create a sorting pattern which makes the female teachers and students of the highest quality attend private schools in urban location. This creates a positive gender matching effect only for urban, private schools. We find support for our theoretical predictions when we test them using Young Lives Survey (YLS) data collected from Andhra Pradesh

<i>In situ </i>isothermal reduction of FeCl₃ in the nanopores of SiO₂ gel matrix

2470-2474Intimately mixed FeCl3 and dextrose are distributed through out the nanometric pores of silica gel. The subsequent heat treatment in the temperature range 900 to 1000oC under nitrogen atmosphere leads to the reduction of FeCl3 to nanometric metallic iron by in Situ hydrogen. The EPR analysis of the heat-treated samples shows the presence of metallic iron. The mechanism of in situ reduction kinetics of FeCl3 in silica gel is nucleation and growth type
