The process that begins around the 6th month of life and continues until the 24th month is called the complementary feeding period. During this period, infants and children start receiving foods that complement breast milk or formula for the first time. The psychosocial factors the infants and children encounter during this period may affect their growth and health in later life.

New derivatives 6a-m with benzimidazole-indole-amide scaffold were developed, synthesized, and assessed for potential inhibitory effects on α-glucosidase and acetylcholinesterase (AChE). These compounds were synthesized by various amine derivatives. With the exception of two compounds, the α-glucosidase inhibitory activities of the title derivatives were more than that of the positive control acarbose.

In this study, we propose identifying potential novel compounds targeting carbonic anhydrase I and II. Herein, we have designed and synthesized new benzimidazole-hydrazide-hydrazones derivatives (4a-4r) to investigate the effects of these synthesized compounds on CA isoenzymes. The compounds' H NMR, C NMR, and HRMS spectra were used to confirm their chemical structures.

New thalidomide analogs have been designed and synthesized by hybridizing the immunomodulatory gutarimide moiety with three antiproliferative nuclei: quinazolinedione, phthalazinedione, and quinoxalinone. The biological results revealed the strong impact of quinazoline derivatives 7 a and 28, and phthalazine based 20 a against HepG-2, MCF-7, PC3, and HCT-116 cell lines, compared to thalidomide. In particular, compound 20 a was the most promising as it had far better biological activity than thalidomide with regard to inhibition of TNF-α, IL-6, caspase 3, COX-I/II, and VEGFR-2, as well as cell cycle arrest, and apoptosis rate enhancement in MCF-7 cells, the most sensitive cell line to the current new molecules.

Infection control measures may be disrupted by inter- or intra-hospital transfers after major disasters. We report the possible outbreak and prevention of vancomycin-resistant Enterococcus spp. (VRE) strains carried by infants transferred to our neonatal intensive care unit from another unit after the earthquake.

Background: Early home intervention for asthma exacerbation (AE) in children is associated with more favorable outcomes. Inhaled short-acting beta agonists (SABA) are the cornerstones of AE treatment.

Objectives: We aimed to determine what proportion of parents administered salbutamol to their children to treat asthma exacerbation at home, and the factors affecting the decision to administer the medication.

Article Synopsis
  • Apraclonidine (APR) is a selective drug used for diagnosing Horner's Syndrome, but it can affect human health negatively due to its accumulation from animal tissue.
  • The study examined how APR interacts with the protein bovine serum albumin (BSA) using various techniques like fluorescence and molecular docking, finding that APR binds weakly to BSA.
  • The thermodynamic analysis indicated that the binding is mainly driven by entropy changes and involves significant hydrophobic interactions, with APR showing higher binding affinity to Drug Site 2 compared to Drug Site 1.

Purpose: The C-reactive protein (CRP) velocity (CRPv) is an indicator of the change in CRP over time. In individuals with sepsis, the second values of CRP and CRPv have been shown to have more importance than the first CRP value measured at admission. This study examined the importance of CRPv for mortality among individuals who were hospitalized in the intensive care unit (ICU).

The World Health Organization reports that 30% of adults worldwide suffer from insomnia, while 10% of people worldwide suffer with various forms of anxiety. The significant negative effects of conventional medications used to treat anxiety and insomnia, such as abuse, addiction, amnesia, and cognitive and sexual dysfunction, have led to an increased preference for naturally derived substances with fewer side effects. Accordingly, in this study, the sedative and anxiolytic effects of -hexane, ethyl acetate (EtOAc), methanol (MeOH) and water extracts of the aerial parts of Duhamel.

End-of-life management of copper indium gallium selenide (CIGS) thin-film solar photovoltaics (PV) panels is crucial due to the necessity of recycling valuable elements such as indium ($400/kg) and gallium ($618/kg), ensuring both economic viability and environmental sustainability. In this study, we analyze the private and external costs of end-of-life management for CIGS PV designed for mass-scale recycling. Our findings reveal that the private and external costs of end-of-life management range from ∼$3.

Background: The aim of this study was to evaluate the biocompatibility and effectiveness in terms of osseointegration of dental implants composed of novel injectable bone grafts with and without ostrich eggshell particles and membrane protein in rabbit femur.

Methods: Sixteen adult male New Zealand rabbits were used in this study. A bone defect was created in each animal's right and left femur, and a dental implant was placed adjacent to the defect.

Purpose: To evaluate the relationship between the development of retinopathy of prematurity (ROP) and neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR).

Material And Methods: The medical records of 153 preterm infants born before the 34th week of gestation, were retrospectively reviewed. Complete blood cell (CBC) and C-reactive protein (CRP) results measured within the first 24 h of life were recorded.

The interaction between Nitisinone (NTBC) and bovine serum albumin (BSA) as the transport protein in a circulating system was investigated for the first time utilizing various analytical (UV-Vis spectrophotometry, fluorescence spectroscopy, dynamic light scattering, and differential scanning calorimetry) and computational (molecular docking and molecular dynamics simulations) methods. The BSA fluorescence intensity was quenched upon interaction with NTBC, and the quenching mechanism was observed as static. The interaction between NTBC and BSA was examined at 288 K, 298 K, and 308 K where the binding constants were found to be 1.

Article Synopsis
  • - The study analyzed data from a randomized trial in Türkiye involving 1,266 volunteers aged 18-55 to assess how previous COVID-19 infections affected adverse events after receiving the TURKOVAC vaccine compared to CoronaVac.
  • - Among participants, 27.7% had a history of COVID-19, with local and systemic adverse events (AEs) occurring in 37.3% and 39% of individuals, respectively, and slightly higher rates were noted shortly after vaccination.
  • - Following the second dose, 1,203 participants were evaluated, showing similar rates of local and systemic AEs for those with and without prior COVID-19 infection, with both TURKOVAC and CoronaVac exhibiting comparable

Article Synopsis
  • Non-small cell lung cancer (NSCLC) is the leading cause of cancer deaths worldwide, and current treatments are inadequate, highlighting the need for new therapies.
  • Ornidazole, a drug primarily used for treating parasitic infections, was studied for its effects on NSCLC cells, showing promise in reducing cell viability, migration, and angiogenesis.
  • The findings suggest Ornidazole could be an effective new treatment option for NSCLC by targeting the molecular pathways involved in tumor growth and spread.

We report herein, the design and synthesis of benzimidazole-oxadiazole derivatives as new inhibitors for vascular endothelial growth factor receptor-2 (VEGFR-2). The designed members were assessed for their in vitro anticancer activity against three cancer cell lines and two normal cell lines; A549, MCF-7, PANC-1, hTERT-HPNE and CCD-19Lu. Compounds 4c and 4d were found to be the most effective compounds against three cancer cell lines.

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.
