Transcriptomic analysis reveals distinct molecular signatures and regulatory networks of osteoarthritic chondrocytes versus mesenchymal stem cells during chondrogenesis.

Background: Recent regenerative studies imply conflicting results on knee osteoarthritic (OA) chondrocytes and mesenchymal stem cells (MSC)-mediated cartilage constructs in terms of compressive properties and tensile strength. This could be attributed to different gene expression patterns between MSC and OA chondrocytes during chondrogenic differentiation. Therefore, we analyzed differentially expressed genes (DEGs) between OA and MSC-derived chondrocytes using bioinformatics tools.

Synthesis, Optical Performance Characterization, and Durability of Electrospun PTFE-PEO Materials for Space Applications.

Passive heat management is crucial in space, especially for extended missions involving protection from sunlight. Thermal coatings with desirable optical properties can drastically reduce the power consumed by active cooling systems, thereby reserving more resources for other critical systems onboard. Specifically, materials with wavelength-dependent reflectance and emittance are desirable for managing incident sunlight and self-cooling by thermal emission.

Photoresponsive Electrospun Fiber Meshes with Switchable Wettability for Effective Fog Water Harvesting in Variable Humidity Conditions.

The global water supply worsens yearly with climate change; therefore, the need for sustainable water resources is growing. One of them is fog water collectors with variable surface wettability, with multifunctional designs for utilization worldwide and to address regions with low humidity levels. Therefore, we created fiber meshes with a photoresponsive switchable surface.

Three-Dimensional Hollow Reduced Graphene Oxide Tube Assembly for Highly Thermally Conductive Phase Change Composites and Efficient Solar-Thermal Energy Conversion.

Due to their extraordinary mechanical strength and electrical and thermal conductivities, graphene fibers and their derivatives have been widely utilized in various functional applications. In this work, we report the synthesis of a three-dimensional (3D) hollow reduced graphene oxide tube assembly (HrGOTA) using the same wet spinning method as graphene fibers. The HrGOTA has high thermal conductivity and displays the unique capability of encapsulating phase change materials for effective solar-thermal energy conversion.

Association of personality traits with performance in military training.

Background: In today's era of asymmetric and unconventional warfare, psychological fitness is equally important as physical fitness. Personality assessment of soldiers, and more so officers who are leaders of men is essential in deciding what makes a good "War asset" The present study was conducted to explore the correlation between personality traits of cadets undergoing training in an Armed Forces Training Academy and their performance in terms of their military and academic pursuits.

Methods: Personality traits of 607 cadets determined using Revised Neuroticism-Extraversion-Openness Personality Inventory (NEO PI-R) were compared and correlated with their performance in terms of Officer Like Qualities (OLQ), Outdoor activities (ODT), Academics, and Extracurricular Activities (ECA).

Is 400 IU per day of Vitamin-D given to healthy well-nourished mothers antenatally enough to prevent neonatal Vitamin-D deficiency?

Background: The incidence of Vitamin D deficiency (VDD) among newborns is very high in India, this is usually secondary to maternal deficiency. Currently Vitamin D at the dose of 400-600 IU/day is being prescribed during pregnancy for prevention. There is paucity of data regarding efficacy of current recommendations in preventing neonatal hypovitaminosis D.

Structural cardiac lesions in transient tachypnea of the newborn.

Background: Transient tachypnea of the newborn (TTN) is considered a benign disorder. Given its self-limiting nature, few studies have looked for associated pathology. This study explores the association of TTN with structural cardiac lesions.

Persistent pulmonary hypertension of the newborn: a review.

Persistent pulmonary hypertension of the newborn (PPHN) is a serious medical emergency in the neonatal period which occurs because of failure of transition of the foetal circulation into the normal circulation. The condition is characterised by persistently elevated pulmonary vascular pressures and despite numerous modalities of treatment available, the condition carries with it a high rate of mortality and morbidity. Early awareness of predisposing conditions and early diagnosis leads to better outcomes in PPHN.

Antibiotic Use in Neonates of Birth-weight < 2000 G Surviving to Discharge.

Background: Symptoms and signs of infection are non-specific in neonates. Hence, neonates, especially low birth-weight and premature ones, often receive empirical antibiotics. This study was conducted to assess the use of antibiotics in newborns with a birth-weight of < 2000 g at a tertiary care service hospital.

Maternal and Neonatal Factors Adversely Affecting Breastfeeding in the Perinatal Period.

Background: Despite its known advantages, breastfeeding rates are low world over. Large number of factors affect breastfeeding. This study was designed to detect maternal and neonatal factors that adversely affect breastfeeding in the perinatal period.

Survival and morbidity in extremely low birth weight (ELBW) infants.

We report the morbidity and mortality in extremely low birth weight neonates (ELBW) from a tertiary care hospital over seven years (1994-2000). Data regarding maternal and neonatal details was obtained from old records, computer database and medical files. Of the 12,807 live births during this period, 137 (1.
