Introduction: The sense of smell is one of the most developed and important senses that forms the bond between the newborn and the mother and allows the newborn to reach the mother's breast. The sense of smell begins to form during intrauterine life, and the sense of smell can be a marking tool for a newborn baby, so that the baby can recognize both his mother and his immediate environment and develop his behaviour accordingly. This is necessary not only for feeding babies but also for them to feel safe and peaceful in their new environment.

This study evaluated the management of dyslipidemia in Turkey with the goal of understanding current diagnosis and treatment patterns, as well as identifying unmet needs in achieving effective low-density lipoprotein cholesterol (LDL-C) targets. Using a Delphi panel consisting of nine expert cardiologists, the study reveals key gaps in dyslipidemia management, particularly in the underutilization of combination therapies, such as statins and PCSK9 inhibitors, which are crucial for achieving LDL-C targets in high-risk patients. The findings indicate that while many patients with very high cardiovascular risk are diagnosed, a significant proportion do not receive optimal treatment to reach LDL-C levels recommended by European guidelines.

Vehicular Ad-hoc Networks (VANETs) are growing into more desirable targets for malicious individuals due to the quick rise in the number of automated vehicles around the roadside. Secure data transfer is necessary for VANETs to preserve the integrity of the entire network. Federated learning (FL) is often suggested as a safe technique for exchanging data among VANETs, however, its capacity to protect private information is constrained.

Background: Posttranslational modifications (PTMs) play critical roles in hepatocellular carcinoma (HCC). However, the locations of PTM-modified sites across protein secondary structures and regulatory patterns in HCC remain largely uncharacterized.

Methods: Total proteome and nine PTMs (phosphorylation, acetylation, crotonylation, ubiquitination, lactylation, N-glycosylation, succinylation, malonylation, and β-hydroxybutyrylation) in tumor sections and paired normal adjacent tissues derived from 18 HCC patients were systematically profiled by 4D-Label free proteomics analysis combined with PTM-based peptide enrichment.

The intersection of electromagnetic radiation and neuronal communication, focusing on the potential role of biophoton emission in brain function and neurodegenerative diseases is an emerging research area. Traditionally, it is believed that neurons encode and communicate information via electrochemical impulses, generating electromagnetic fields detectable by EEG and MEG. Recent discoveries indicate that neurons may also emit biophotons, suggesting an additional communication channel alongside the regular synaptic interactions.

Aim: This study aimed to investigate the relationship between PET and CT parameters and sarcopenia, adipose tissue, and tumor metabolism in esophageal carcinoma(EC) and its impact on survival in EC.

Method: Our study included 122 EC patients who underwent PET/CT for staging. Muscle and adipose tissue characteristics were evaluated, including lumbar(L3) and cervical(C3) muscle areas, psoas major(PM) and sternocleidomastoid muscle(SCM) parameters, and PET parameters for visceral and subcutaneous adipose tissue(SAT).

Growing evidence reveals that microglia activation and neuroinflammatory responses trigger cell loss in the brain. Histamine is a critical neurotransmitter and promotes inflammatory responses; thus, the histaminergic system is a potential target for treating neurodegenerative processes. JNJ-7777120, a histamine H4 receptor (HR) antagonist, has been shown to alleviate inflammation, brain damage, and behavioral deficits effectively, but there is no report on its role in brain trauma.

Purpose: This retrospective study aimed to assess ossification patterns and synchondrosis fusion timelines of the C1 and C2 vertebrae in pediatric age group, to help differentiate injuries from normal variations and serve as a guide when evaluating incompletely fused synchondrosis.

Materials And Methods: The study analyzed 432 CT examinations of children aged 0-72 months, conducted at a single institution between January 2010 and January 2018. The focus was assessment of the visibility and fusion of the three ossification centers and three synchondroses of the atlas, and six ossification centers and four synchondroses of the axis, based on age.
