Current trends in physical and physiological profile of elite WKF karate athletes: a systematic review.

Background: This qualitative analysis aimed to: identify the physical and physiological factors that characterize elite WKF kumite and kata athletes, identify testing protocols that are used to examine the above mentioned profiles of WKF karatekas and indicate the variables that are significant for elite-level performance.

Methods: A search of electronic databases (PubMed, EBSCO, Scopus) was conducted to identify all studies on physical and physiological profile in elite karatekas from 2012 to 2024. A JBI Qualitative Data Extraction Tool for systematic reviews of qualitative evidence was fulfilled in order to determine which variables should be extracted.

Effects of a 12 Week Ketogenic Diet Intervention on Obese and Overweight Females with Glucose and Lipid Metabolism Disturbance.

Background/objectives: We evaluated the effects of a 12-week hypocaloric ketogenic diet (KD) on glucose and lipid metabolism, as well as body mass, in overweight, obese, and healthy-weight females. One hundred adult females completed the study, including 64 obese (97.99 ± 11.

Unexpected Formation of a Chiral spiro-system in the Reaction of the Dilithium Derivative of Hexafluorocumyl Alcohol with N-(t-butylsulfenyl)phthalimide.

An unexpected course of the reaction of hexafluorocumyl alcohol dilithium derivative 2 with N-(t-butylsulfenyl)phthalimide (3) has been presented. The process proceeded under mild conditions and resulted in previously undescribed chiral spiro-system- 3',3'-bis(trifluoromethyl)-3H,3'H-1,1'-spirobis(isobenzofuran)-3-one (5) as the only product. A detailed spectral analysis of the product has been provided, and mechanistic aspects have been investigated.

Effects of Extrinsic and Intrinsic Motivation on Selective Activation of Shoulder Girdle Muscles During the Barbell Bench Press Exercise.

This study aimed to investigate the effects of intrinsic and extrinsic motivation on selective muscle activation of the shoulder girdle during the barbell bench press. Specifically, this research focused on how attentional focus on individual muscles, such as the anterior deltoid (AD), pectoralis major (PM), and triceps brachii long (TBL), could influence their electromyographic (EMG) activity during the exercise. : Twelve male participants, with at least five years of strength training experience, performed bench press exercises under two conditions: with extrinsic motivation (no specific focus on muscle activity) and with intrinsic motivation (internal focus on specific muscles).

The engagement of Ras/Raf/MEK/ERK and PLCγ1/PKC pathways regulated by TrkB receptor in resistance of glioma cells to elimination upon apoptosis induction.

The most aggressive tumors of human central nervous system are anaplastic astrocytoma (AA, III grade) and glioblastoma multiforme (GBM, IV grade) with an extremely bad prognosis. Their malignant character and resistance to standard therapy are correlated to the over-expression of survival pathways such as Ras/Raf/MEK/ERK and PLCγ1/PKC regulated by TrkB receptor. Therefore, the aim of this study was to investigate the engagement of those pathways in human glioma cells resistance for apoptosis induction by Temozolomide treatment.
