Synthesis of AgInS2 nanoparticles Directly in Poly (3-hexyl thiophene) (P3HT) Matrix: Photoluminescence quenching studies

Inorganic semiconductor AgInS, nanoparticles and P3HT/AgInS2 composite was synthesized by decomposition of silver indium xanthate. The synthesized nanoparticles and composite were characterized by XRD and UV-Vis spectroscopy. PL quenching of the composite demonstrate that the electron transfer from polymer to inorganic NPs through ex-situ solution blending is less efficient in PL quenching as compared to in-situ synthesis

Extensive intraductal component positive carcinoma of breast: two year study with special reference to ER/PR/HER2NEU/Ki67 in a tertiary care centre of Barak Valley

Background: Extensive intraductal component positive carcinoma (EICPC) of breast is defined by Schnitt et al as-A. 25% or more of Ductal carcinoma in situ (DCIS) is present along the invasive lesion and DCIS is also present outside the area of invasive carcinoma. B. EICPC also include carcinomas in which DCIS is associated with a “small” (approximately 10 mm or less) invasive carcinoma or carcinomas. In Extensive Intraductal Carcinoma (EIDC) most of the cases were associated with recurrence when surgical margin status is not evaluated or focally involved. Our objective was to study the prevalence of EIDC and expression of estrogen receptor (ER)/progesterone receptor (PR)/human epidermal growth factor (HER2NEU)/Ki67(antigen identified by monoclonal antibody KI67) in those cases.Methods: It was a retrospective cross sectional study conducted over a period of 2017 to August 2019.All the histologically confirmed cases of EIDC was retrieved from the institute.Results: Out of 65 cases of invasive carcinoma 17 (26.1%) cases were positive for EICPC. Age of patients ranged from 27 to 73years with mean age of 43 years and 5 patients (29.4%) were postmenopausal. Most of the cases  i.e. 6(35.2%) had a ER+/PR+/HER2NEU- status with most of the cases having high 6(47%)Ki-67 index. According to the BLOOM RICHARDSON GRADING 14 cases were grade II (82.3%) and 3 cases were grade I (17.7%) and in pT and pN staging majority were stage pT1 - 7 (41.1%). Most of the cases were mastectomy cases 11 (64.4%) with a base free status except in one lumpectomy case where margin was involved.Conclusions: In this study majority of the cases were ER+//PR+/HER2NEU- with most of the cases having high Ki67 index. Evaluation of EIDC, along with the negative margin status is important to prevent recurrence

A two years study of histopathological spectrum of skin adnexal tumors in a tertiary care centre of Southern Assam, India

Background: Skin adnexal tumors (SAT) encompass a wide spectrum of benign and malignant tumors that differentiate toward one or more adnexal structures found in normal skin. Overall incidence of SATs is low yet they can be challenging to diagnose. Our study aims at analysis of histopathological spectrum of various SATs according to age, sex and anatomic locations along with histopathological features.Methods: It was a retrospective cross-sectional study conducted over a period of 2 years from June 2017 to May 2019. All cases were retrieved from department registries and analyzed.Results: Out of the total 4013 biopsies, 25 cases were diagnosed as SATs comprising 44% of tumors with eccrine sweat gland differentiation followed by tumors showing hair follicle differentiation (32%), sebaceous differentiation (16%) and apocrine gland differentiation (8%). The age ranged from 4 years to 68 years and male: female ratio was 1:1.5. Most of the tumors were benign (84%) while only 16% were malignant. Pilomatricoma (19%) was the most common benign tumor while sebaceous carcinoma (75%) was the most common malignant tumor.Conclusions: Skin adnexal tumors are relatively rare neoplasm. Malignant cases are less common than benign ones. Histopathology is quite essential for diagnostic point of view

Burden, maternal risk factors, and fetal outcomes in twin pregnancies: a retrospective observational study

Background: Twin pregnancies present significant challenges for obstetricians worldwide. Although they account for a relatively small percentage of global births, their occurrence varies across different regions. The increasing utilization of assisted reproduction techniques and the advancing maternal age contribute to the growing incidence of twin pregnancies. As a result, it is essential to understand the implications and risks associated with multiple gestations. The objective was to determine the burden of twin pregnancies, identify maternal risk factors, assess fetal outcomes, and explore potential associations between these factors. Methods: Data were collected from hospital records, including information on maternal age, parity, method of conception, gestational age, pregestational body mass index (BMI), and family history. Maternal and fetal complications, mode of delivery, and high-risk conditions in the fetuses were documented. Statistical analysis was performed using the Fisher-exact test. Results: The study included 78 twin pregnancies. The majority of women (78.2%) fell within the age range of 21-30 years. The majority of women (70.5%) had a normal pregestational BMI. Preterm births occurred in 24.3% of twin pregnancies. Hypertensive disorders (24.0%) and foetal malpresentation (38.0%) were common indications for cesarean section. Fetal complications included intrauterine growth restriction (11.5%), birth weight discordance (25.0%), early neonatal deaths (14.7%), and low APGAR scores (16.0%). Conclusions: Twin pregnancies present challenges due to the increased risks of maternal complications, preterm birth, and adverse fetal outcomes. The study emphasizes the need for careful management and monitoring of twin pregnancies to improve outcomes

Study on the ameliorating effect of aqueous extract of Moringa oleifera on Ganga water

The quality of  surface water is deteriorating day by day due to various anthropogenic activities. Ganga water is assumed polluted almost in the entire strech of river. The medicinal plants may be useful for amelioration of pollution. The present work deals with the study of several chemical characteristics as well as microbial examination of water samples taken from few sites of Ganga river namely Krishna Ghat, Kali Ghat and N.I.T Ghat (Gandhi Ghat) at Patna. The study was foccused on the evaluation of antimicrobial effect of Moringa oleifera (sahjan) leaves extract in the Ganga water. The aqueous leaves extract of different concentrations (0.1%, 0.16%, 0.23%, 0.3%) showed ameliorating results on pH and chloride content of water as well as microbial activity. Significant ameliorating results were observed on pH and chloride content of water. pH was reduced from 8.1 to 7.4 and chloride was reduced from 82.36 mg/l to 48.14 mg/l under plant extract treatment. Colony Forming Unit (CFU) was assessed by standard plate count (SPC) method and was found to be 468 CFU/ml for raw water, which was reduced to 143 CFU/ml when treated with plant extract. Similar decreasing trend was observed in case of MPN of coliform. So extract of Moringa oleifera may also be applied to purify drinking water. Morever it will be cheaper for the people in comparision to other purification devices
