Background: Intertrochanteric femur fractures are common in the elderly and a growing public health concern. Surgical fixation remains the gold standard, with proximal femoral nail (PFN) and trochanteric fixation nail (TFN) being the most commonly used implants. This study compares the functional outcomes and complications of PFN and TFN in the Indian population.

Glucose-dependent insulin delivery systems have been recognized as a promising approach for controlling blood sugar levels in individuals with diabetes mellitus (DM). Recently, titanium dioxide nanoparticles have garnered huge attention in scientific research for their small size and effective drug delivery capabilities. In this study, we developed alizarin (AL)-capped phenylboronic acid (PBA)-functionalized titanium dioxide nanoparticles (TiO) for glucose-sensitive insulin delivery (TiO-PBA-INS-AL) aiming to manage both blood sugar levels and its associated organ pathology in DM.

Here, we first synthesized carbon dots (CDs) from taurine and then a nanohybrid with ceria (CeO) nanoparticles using thermal decomposition method for checking their antineoplastic efficacy against human triple negative mammary carcinoma cells, MDA-MB-231. The in vitro study demonstrated significant dose-dependent antineoplastic activity of the nanohybrids within a range of concentration from 10 to 50 μg/mL after 48 h of treatment. The cellular morphology analysis clearly depicted substantial amount of cell death which seems to stem from increased intracellular reactive oxygen species (ROS) production.

Article Synopsis
  • The study investigates the hepatoprotective (liver-protecting) properties of a popular Ayurvedic herb by analyzing its phytochemicals using targeted metabolomics.
  • Different fractions of the herb's hydro-alcoholic extract were tested for antioxidant and protective effects on liver cells (HepG2), with the n-butanol fraction showing the best results.
  • UPLC-QTOF-MS analysis identified 17 secondary metabolites in the active fraction, some of which may inhibit the CYP2E1 enzyme, potentially reducing toxicity from APAP (acetaminophen) in liver cells.

Article Synopsis
  • Nanoceria (NC) is being explored for its effectiveness in drug delivery and reducing oxidative stress, particularly in diabetes treatment.
  • The researchers created a dextran-capped insulin nanoparticle (NC-PBA-INS-Dex) that responds to glucose levels, facilitating insulin delivery and combating oxidative stress in diabetic conditions.
  • The study showed that NC-PBA-INS-Dex enhances insulin delivery and effectiveness, maintaining stable blood sugar levels for longer periods and exhibiting potential for both oral and systemic administration in diabetic animals.

Aim: The study aimed to comparatively evaluate the effect of eugenol exposure time on the micro-shear bond strength (μ-SBS) of etch-and-rinse and a self-etch adhesive to dentin.

Materials And Methods: One hundred and twelve teeth samples were prepared from bisectioning 56 freshly extracted human mandibular molars and were randomly divided into 14 subgroups of 8 samples each (n = 8). Three subgroups containing eugenol and a noneugenol-based restorative material were placed on the dentin surface and left for 24 h, 7 days, and 14 days, respectively, and were compared to a control.

Antimicrobial resistance (AMR) is a serious and most urgent global threat to human health. AMR is one of today's biggest difficulties in the health system and has the potential to harm people at any stage of life, making it a severe public health issue. There must be fewer antimicrobial medicines available to treat diseases given the rise in antibiotic-resistant organisms.

These days carbon dots have been developed for multiple biomedical applications. In the current study, the transfection potential of synthesized carbon dots from single biopolymers such as chitosan, PEI-2kDa, and PEI-25kDa (S-CDs, PEI2-CDs, and PEI25-CDs) and by combining two biopolymers (CP2-CDs and CP25-CDs) through a bottom-up approach have been investigated. The characterization studies revealed successful synthesis of fluorescent, positively charged carbon dots <20 nm in size.

Breast cancer (BC) is one of the most heterogeneous groups of cancer. As every biotype of BC is unique and presents a particular "omic" signature, they are increasingly characterized nowadays with novel mass spectrometry (MS) strategies. BC therapeutic approaches are primarily based on the two features of human epidermal growth factor receptor 2 (HER2) and estrogen receptor (ER) positivity.

Melatonin, the pineal hormone, is synthesized and secreted rhythmically in accordance with various environmental cues especially photo-thermal conditions. The reproductive physiology of seasonal breeders is synchronized with the surroundings by melatonin as a neuroendocrine mediator to acts as an important factor in fish reproduction. However, the data on the participation of melatonin in male reproduction and the putative interaction with the process of spermatogenesis in fish is scarce till date.

Melatonin, a pineal hormone, has potential role on steroidogenesis, growth and maturation of sperm and ovum during gametogenesis. The possible use of this indolamine as an antioxidant in the production of good quality gametes opens up a new area of current research. Nowadays, a large number of reproductive dysfunctions like infertility and failure in fertilization due to gametic malformations are major concern worldwide.

Recently, different natural bioactive compounds have been used as anticancer agents for their various therapeutic benefits and non-toxic nature to other organs. However, they have various restrictions in preclinical and clinical studies due to their non-targeting nature and insufficient bioavailability. As a result, a zinc oxide nanoparticle (ZnO) based drug delivery medium was constructed which has good bio-compatibility and bio-degradability.

Heavy metal-contaminated water can be effectively treated using adsorbents made from abundantly available biomass. The present investigation was carried out to adsorb Cd(II) from synthetic solution by banana pseudo-stem (BP) and Moringa oleifera stem bark (MB). Adsorption efficiencies of both adsorbents were studied in the batch reactor by conducting experiments to determine the consequences of changes of pH, adsorbent dosages, initial Cd(II) concentrations, incubation time, and temperature.

Aims: Synthesis of novel drug delivery system for targeted delivery of cuminaldehyde to breast cancer cells and the subsequent analyses of anti-neoplastic potential of the drug.

Main Methods: 3-carboxy-phenyl boronic acid (PBA) conjugated and polyacrylic acid (PAA) gated mesoporous silica nanoparticles (MSNs) were synthesized for the targeted delivery of cuminaldehyde (CUM) to breast cancer cells. Enhancement of anti-neoplastic effects of cuminaldehyde (4-isopropylbenzaldehyde) by the nanoconjugates was assessed.
