This study aimed to determine the efficacy of red pine and larch pine needles powder at different doses on productive performance, egg quality, hatching parameters, total fatty acid and cholesterol levels of laying quails. A total of 126 (84 ♀ and 42 ♂) 20-week-old laying quail were randomly distributed into seven experimental diets with three replicates of six (four female and two male) birds per cage. The groups were fed a basal diet (CON group), a basal diet with red pine needle powder (RPNP group) (1.

Article Synopsis
  • - A study was conducted on 240 pregnant women (120 with pregestational diabetes) to examine changes in systemic inflammatory indices and APRI scores during pregnancy, and their association with perinatal outcomes.
  • - Results indicated significant alterations in inflammatory markers across trimesters, with notable cut-off values identified for predicting low birth weight and preterm delivery based on certain indices.
  • - The findings suggest that monitoring the NLR in the first trimester and the APRI score in the last trimester could help predict perinatal outcomes in pregnancies complicated by pregestational diabetes.

Pulmonary sequestration is uncommon congenital malformation. It is important to consider pulmonary sequestration even in young adults presenting with recurrent pneumonic symptoms because prompt surgical intervention is both feasible and curative. Moreover, in health settings lacking CT/MRI angiography service, pulmonary sequestration can be easily misdiagnosed as smear negative pulmonary tuberculosis.

Traumatic brain injury (TBI) is a risk factor for neurodegeneration and cognitive decline, yet the underlying pathophysiologic mechanisms are incompletely understood. This gap in knowledge is in part related to the lack of analytic methods to account for cortical lesions in prior neuroimaging studies. The objective of this study was to develop a lesion detection tool and apply it to an investigation of longitudinal changes in brain structure among individuals with chronic TBI.

Protein kinases regulate cellular activities and make up over 60% of oncoproteins and proto-oncoproteins. Among these kinases, FLT3 is a member of class III receptor tyrosine kinase family which is abundantly expressed in individuals with acute leukemia. Our previous oxindole-based hit has a particular affinity toward FLT3 (IC = 2.

Article Synopsis
  • This study looked at how well a surgical method called resection and extended end-to-end anastomosis works for babies with a condition called aortic coarctation.
  • It compared the results between two groups: very young babies (neonates) and infants up to a year old.
  • Both groups showed improvements after surgery, and the method was effective for reducing problems in the aorta for both ages.

  • Cyanotic congenital heart diseases make up 40-45% of congenital heart conditions, and for some patients, modified BT (MBT) and central shunt (CS) are common procedures when primary repair isn’t suitable.
  • The study analyzed data from 62 pediatric patients who underwent these procedures, focusing on factors such as demographics, surgery details, and postoperative outcomes, categorizing patients based on cardiac anatomy and other conditions.
  • Results showed no significant differences in immediate surgical outcomes between MBT and CS, but a high incidence of congestive heart failure was associated with increased mortality, highlighting the importance of shunt size and placement in reducing risks.

Purpose: Internal medicine residents care for clinically complex older adults and may experience increased moral distress due to knowledge gaps, time constraints, and institutional barriers. We conducted a phenomenological study to explore residents' experiences and challenges through the lens of uncertainty.

Methods: Between January and March 2022, six focus groups were conducted comprising a total of 13 internal medicine residents in postgraduate years 2 and 3, who had completed a required 2-week geriatrics rotation.

A series of biologically active novel Mannich bases containing with a 1-1,2,4-triazole-5-one ring were developed to evaluate the cytotoxic activity. For this purpose, the synthesized Schiff Bases () were reacted with formaldehyde and morpholine, which is a secondary amine to yield novel -Mannich bases () the Mannich reaction. The structures of the compounds () were determined structurally employing H/C-NMR, IR and elemental analysis.

Background: Severe burn injuries are a major health problem globally. A profound and prolonged hypermetabolic response develops in severe burn injuries and it is crucial to monitor the patients' energy requirements in order to meet them adequately. The aim of the present study was to examine the energy changes during the acute phase using the indirect calorimetry (IC) method in severe burn patients.

Introduction: We aimed to investigate the effects of colchicine use on first and second trimester screening markers in pregnancies complicated with familial Mediterranean fever (FMF) and to evaluate the overall impact of these effects on perinatal outcomes.

Methods: A retrospective case-control study was conducted in pregnancies complicated with FMF using colchicine and healthy pregnancies as controls without any defined risk factors and medication use. Biochemical markers for the aneuploidy screening, including free ß-hCG and PAPP-A in the first trimester, and AFP, HCG, and unconjugated estriol (uE3) in the second trimester, were recorded, and MoM levels of these markers were compared between the FMF and control groups.

Purpose: To evaluate the level of eosinophil count in Covid-19 pregnant patients as a cost-effective tool for aiding in diagnosis, differential diagnosis, and prognosis and, to assess whether eosinopenia could be similar or superior to lymphopenia in pregnancy with Covid-19.

Methods: Retrospective case-control study was conducted including pregnant women tested simultaneously for SARS-CoV-2 by RT-PCR and complete blood count (CBC). Eosinophil counts (EOS), lymphocytes (LYM), neutrophils (NEU) with calculation of EOS/LYM ratio, EOS/NEU ratio, NEU/LYM ratio, LYM/NEU ratio (LNR), eosinopenia, and lymphopenia were compared between the groups.

Background: Acute kidney injury (AKI) is one of the common complications, associated with high mortality and morbidity in patients with burn injuries. This study aimed to determine the frequency of AKI development, its affective factors, and mortality rates according to kidney disease improving global outcomes (KDIGO) criteria in the burn patients.

Methods: The study included patients who are hospitalized for at least 48 h and aged >18 years, whereas patients with a renal transplant, chronic renal failure, undergoing hemodialysis, <18 years of age, with a glomerular filtration rate of <15 on admission, and toxic epidermal necrolysis was excluded from the study.

The structure-based design introduced indoles as an essential motif in designing new selective estrogen receptor modulators employed for treating breast cancer. Therefore, here, a series of synthesized vanillin-substituted indolin-2-ones were screened against the NCI-60 cancer cell panel followed by in vivo, in vitro, and in silico studies. Physicochemical parameters were evaluated with HPLC and SwissADME tools.

Although the etiopathogenesis of Behçet's disease is not known, studies conducted in different populations show that it is a multifactorial disease that is thought to develop as a result of the interaction of environmental and genetic factors. IL-17 is thought to induce the neutrophilic inflammation and the tissue damage mediated by immune response in patients. Polymorphisms in the gene region encoding IL-17 and IL-17R molecules may play a critical role in the pathogenesis of the disease and contribute to the elucidation of disease mechanism.

Native valve aortic endocarditis is rarely seen in the paediatric population. Although, the first-line of treatment is medical, surgical intervention may be indicated in patients with unrepairable valvular and subvalvular disease. Recently, the aortic valve neocuspidization (AVNeo) procedure has gained popularity both in adult and children in whom other repair techniques are not feasible.

The use of textiles in soft robotics is gaining popularity because of the advantages textiles offer over other materials in terms of weight, conformability, and ease of manufacture. The purpose of this research is to examine the stitching process used to construct fabric-based pneumatic bending actuators as well as the effect of segment types on the actuators' properties when used in soft robotic glove applications. To impart bending motion to actuators, two techniques have been used: asymmetry between weave and weft knit fabric layers and mechanical anisotropy between these two textiles.
