Magnetite nanoparticles have attracted the attention of researchers for biomedical uses, but their impacts on the reproductive system did not report. Here, we have studied the possible attenuation efficiency of quercetin against magnetite nanoparticles-induced apoptosis in ovarian. Forty female rats were divided equally into control, quercetin (100 mg/kg), magnetite nanoparticles (50 mg/kg), and magnetite nanoparticles+quercetin, where all rats received their doses for four weeks.

Avian pox is a disease that has devastating impacts on both poultry and wild bird species. Avian pox is caused by various strains of avipoxviruses (APV). Nevertheless, the virus has been detected in pigeons and chickens that are raised in backyard areas, leading to substantial financial damage for small-scale producers.

Background: Female pattern hair loss (FPHL) is widely common and negatively impacts the quality of life. FPHL is more challenging to treat than male pattern hair loss with minoxidil being the gold standard treatment. Several studies used 17α-estradiol solution for treating FPHL with variable results either alone or combined with minoxidil.

The case of the monozygotic (MZ) twin as a suspect demonstrates a practical problem in forensic casework. As the MZ twins are genetically identical, they share the same short tandem repeat (STR) profile. Many studies showed that older MZ twins have significant differences in overall content and genomic distribution of methylation between them.

Article Synopsis
  • The study investigates the effects of nanoencapsulated multi-strain probiotics on the health and performance of broiler chickens, specifically focusing on their ability to combat Salmonella Typhimurium.
  • A total of 2,800 Ross 308 chicks were divided into groups receiving different probiotic treatments, including standard and nanoencapsulated forms, before being challenged with Salmonella at 22 days old.
  • Results showed that birds fed the higher doses of nanoencapsulated probiotics (BLB-NPs II and III) had improved weight gain, enhanced immune response, lower Salmonella counts, and greater populations of beneficial gut bacteria compared to the control group.

  • Acinetobacter baumannii is a dangerous pathogen that poses serious infection risks, especially to immunocompromised individuals, and is known for its resistance to most antibiotics.
  • This study analyzed two multidrug-resistant A. baumannii isolates from neonates in a NICU in Egypt, focusing on their antibiotic resistance mechanisms using techniques like whole-genome sequencing and multilocus sequence typing.
  • Both isolates were highly resistant but shared some resistance genes, belonged to the same genetic sequence type (ST931), and exhibited various other genetic elements that contribute to their resistance.

  • Triple-negative breast cancer (TNBC) patients often undergo neoadjuvant systemic therapy (NAST) to improve treatment outcomes.
  • A study analyzed multiparametric MRI scans from 163 TNBC patients at different stages of NAST to see if radiomic models could predict the likelihood of achieving a pathologic complete response (pCR).
  • The best predictive model, based on changes in MRI features after two cycles of treatment, showed a strong ability to forecast pCR with high accuracy, indicating that MRI could be useful for early treatment response assessments in TNBC.

Background: Type 2 diabetes is an endocrine disorder characterized by compromised insulin sensitivity that eventually leads to overt disease. Adipose stem cells (ASCs) showed promising potency in improving type 2 diabetes and its complications through their immunomodulatory and differentiation capabilities. However, the hyperglycaemia of the diabetic microenvironment may exert a detrimental effect on the functionality of ASCs.

Purpose: This study sought to find out if a 6-week accommodating variable-resistance (AcVR) training might enhance muscle architecture, peak torque, and functional performance in patients with juvenile idiopathic arthritis (Juv-IA).

Methods: Fifty-eight patients with polyarticular Juv-IA (aged 12-18 years) were involved in a randomized controlled trial. They were allocated into two groups: the AcVR group ( = 29; underwent AcVR training, and the control group ( = 29; received the usual exercise regimen).

A radiation therapist (RTT) is a key member of the radiation oncology team responsible for delivering radiation and providing direct patient care to individuals undergoing cancer treatment. Stony Brook University's School of Health Professions, in collaboration with Mount Sinai Health System's Department of Radiation Oncology, offers a unique RTT Program structure: a 4-year baccalaureate degree followed by a 12-month clinical non-credit, non-degree certificate. The RTT Program embeds concepts such as the theory of gynecologic malignancies, introduced in the didactic setting and mastered in the clinical environment.

Article Synopsis
  • The study investigates the use of diffusion tensor imaging (DTI) to assess treatment response in women with triple-negative breast cancer (TNBC) undergoing neoadjuvant systemic treatment (NAST).
  • Out of 86 participants, 47% achieved a pathologic complete response (pCR), and DTI parameters showed significant differences between pCR and non-pCR patients during treatment.
  • Findings suggest that DTI measurements, particularly of the peritumoral region, could be valuable in predicting treatment outcomes for TNBC patients.

Article Synopsis
  • A deep learning model was trained to predict how well patients with triple negative breast cancer (TNBC) respond to neoadjuvant systemic therapy (NAST) using MRI scans taken before and after treatment.
  • The model showed strong predictive performance, achieving high accuracy scores (AUCs) for different testing groups, indicating it can reliably identify patients who have a pathologic complete response (pCR).
  • This technology could lead to more personalized treatment strategies for TNBC patients by allowing early identification of those likely to benefit from NAST based on MRI data.

Background: The severity of chronic hepatitis C and susceptibility to hepatocellular carcinoma (HCC) are associated with genetic variations within vitamin D receptor (VDR) in several populations. This study aims to determine the significance of the VDRs (rs2228570, rs3782905, rs11568820) and DBP (rs7041) for the susceptibility to HCC in Egyptian patients with chronic HCV infection and their effect on the progression of liver cirrhosis to carcinogenesis.

Methods: Single nucleotide polymorphisms (SNPs) VDR (rs2228570, rs3782905), and DBP rs7041 were genotyped using restriction fragment length-PCR (RFLP-PCR) technique and VDR rs11568820 was genotyped using single strand polymorphism PCR (SSP PCR).

Background: P-Element-induced wimpy testis (PIWI) proteins, when in combination with PIWI-interacting RNA (piRNA), are engaged in the epigenetic regulation of gene expression in germline cells. Different types of tumour cells have been found to exhibit abnormal expression of piRNA, PIWIL-mRNAs, and proteins. We aimed to determine the mRNA expression profiles of PIWIL1, PIWIL2, PIWIL3, & PIWIL4, in hepatocellular carcinoma patients, and to associate their expression patterns with clinicopathological features.

Urolithiasis is one of most common renal disorders, characterized by the formation of kidney stones (renal calculi) through the crystallization process within the urinary system. The frequently observed renal calculi are calcium oxalate renal calculi and treatment is done by shock wave method or lithotripsy which is harmful for other cells of the internal system. The objective of this work was to evaluate in vitro diagnosis of calcium oxalate kidney stones in the aqueous solution of Bryophyllum pinnatum.
