Comparison of stop-jump muscle synergies in amateur basketball players with and without asymptomatic patellar tendon abnormalities during simulated games.

: Asymptomatic patellar tendon abnormality (APTA) is considered a precursor to patellar tendinopathy (PT), but its pathogenesis remains unclear, especially regarding changes in muscle coordination. Therefore, it is essential to explore the muscle synergy patterns in individuals with APTA. This study recorded sEMG data during stop-jump tasks in 8 APTA and 8 healthy amateur male basketball players in a simulated basketball game.

Cognitive Impairment in Psychotic Disorders Is Associated with Brain Reductive Stress and Impaired Energy Metabolism as Measured by 31P Magnetic Resonance Spectroscopy.

Background And Hypothesis: Convergent evidence shows the presence of brain metabolic abnormalities in psychotic disorders. This study examined brain reductive stress and energy metabolism in people with psychotic disorders with impaired or average range cognition. We hypothesized that global cognitive impairment would be associated with greater brain metabolic dysregulation.

Supernumerary Muscles in the Leg and Foot: A Review of Their Types, Frequency, and Clinical Implications.

Variations of the ankle anatomy are infrequent and exist as supernumerary muscles and tendons. Often understudied and overlooked, their presence can cause many complications of the lower extremity. These muscles, although often asymptomatic, can cause great pain and complications such as tenosynovitis, tarsal tunnel syndrome, lateral ankle instability, and ankle pain when they impinge on the normal anatomy of the patient.

From cytogenetics to cytogenomics: a new era in the diagnosis of chromosomal abnormalities in domestic animals.

Identification of chromosomal abnormalities is an important issue in animal breeding and veterinary medicine. Routine cytogenetic diagnosis of domestic animals began in the 1960s with the aim of identifying carriers of centric fusion between chromosome 1 and 29 in cattle. In the 1970s, chromosome banding techniques were introduced, and in the 1980s, the first cytogenomic techniques, based on the development of locus- and chromosome-specific probes, were used.

Molecular Modeling on Duplexes with Threose-Based TNA and TPhoNA Reveals Structural Basis for Different Hybridization Affinity toward Complementary Natural Nucleic Acids.

Synthetic nucleic acids, also defined as xenobiotic nucleic acids (XNAs), opened an avenue to address the limitations of nucleic acid therapeutics and the development of alternative carriers for genetic information in biotechnological applications. Two related XNA systems of high interest are the α-l-threose nucleic acid (TNA) and (3'-2') phosphonomethyl threosyl nucleic acid (tPhoNA), where TNAs show potential in antisense applications, whereas tPhoNAs are investigated for their predisposition toward orthogonal genetic systems. We present predictions on helical models of TNA and tPhoNA chemistry in homoduplexes and in complex with native ribose chemistries.

Exocrine pancreatic insufficiency as an unusual extrarenal manifestation of proximal renal tubular acidosis associated with a novel SLC4A4 mutation.

Autosomal recessive proximal renal tubular acidosis (AR-pRTA) with ocular abnormalities is a rare syndrome caused by variants in the SLC4A4 gene, which encodes Na/HCO3 cotransporter (NBCe1). The syndrome primarily affects the kidneys, but also causes extra-renal manifestations. Pancreatic type NBCe1 is located at the basolateral membrane of the pancreatic ductal cells and together with CFTR chloride channel, it is involved in bicarbonate secretion.

Modulation of placental angiogenesis by metformin in a rat model of gestational diabetes.

Gestational diabetes mellitus (GDM) significantly disrupts placental structure and function, leading to complications such as intrauterine growth restriction (IUGR) and preeclampsia. This study aimed to investigate the effects of GDM on placental histology, angiogenesis, and oxidative stress, as well as evaluate metformin's protective role in mitigating these changes. A total of 60 pregnant Sprague-Dawley rats were divided into four groups: control, metformin-treated, GDM, and GDM with metformin.

Outcomes of electrical injuries in the emergency department: epidemiology, severity predictors, and chronic sequelae.

Introduction: Electrical injuries (EIs) represent a significant clinical challenge due to their complex pathophysiology and variable presentation, ranging from minor burns to severe internal organ damage. Despite their prevalence in both; domestic and occupational settings, there remains a rareness of systematic guidelines and comprehensive literature to aid clinicians in effectively managing these injuries. Understanding these factors is crucial for developing protocols that can mitigate the risk of delayed complications, such as cardiac arrhythmias, in patients who initially appear stable.

Severe bradycardia in patients with obstructive sleep apnoea and good early response to CPAP.

Background: Obstructive sleep apnoea (OSA) may lead to heart rhythm abnormalities including bradycardia. Our aim was to ascertain clinical and echocardiographic parameters in patients with OSA in whom severe bradycardia was detected in an outpatient setting, as well as to evaluate the efficacy of CPAP therapy on heart rate normalization at the early stages of treatment.

Methods: Fifteen patients mild, moderate or severe OSA and concomitant bradycardia were enrolled.

Immuno-oncology in the daily practice.

Purpose Of Review: Immune checkpoint inhibitors (ICI) have become an integral part of oncology treatment. ICI currently has approval for more than thirty tumor types with proven efficacy. However, ICI can expose patients to inflammatory side effects, such as immuno-related adverse events (irAE).

Spontaneous Transformation from Lung Adenocarcinoma to MYC-amplified Large Cell Neuroendocrine Carcinoma.

Recent studies suggest that lung adenocarcinoma cells are closely associated with the tumorigenesis of large-cell neuroendocrine carcinoma via cellular transformation. However, morphological evidence, along with genetic abnormalities before, during, and after transformation, is quite limited. We present here a case of combined large-cell neuroendocrine carcinoma and adenocarcinoma exhibiting acinar and solid patterns.

Dendritic alterations precede age-related dysphagia and nucleus ambiguus motor neuron death.

Motor neurons (MNs) within the nucleus ambiguus innervate the skeletal muscles of the larynx, pharynx and oesophagus, which are essential for swallow. Disordered swallow (dysphagia) is a serious problem in elderly humans, increasing the risk of aspiration, a key contributor to mortality. Despite this importance, very little is known about the pathophysiology of ageing dysphagia and the relative importance of frank muscle weakness compared to timing/activation abnormalities.

Extending Badger's rule. I. The relationship between energy and structure in hydrogen bonds.

We derive a new expression for the strength of a hydrogen bond (VHB) in terms of the elongation of the covalent bond of the donor fragment participating in the hydrogen bond (ΔrHB) and the intermolecular coordinates R (separation between the heavy atoms) and θ (deviation of the hydrogen bond from linearity). The expression includes components describing the covalent D-H bond of the hydrogen bond donor via a Morse potential, the Pauli repulsion, and electrostatic interactions between the constituent fragments using a linear expansion of their dipole moment and a quadratic expansion of their polarizability tensor. We fitted the parameters of the model using ab initio electronic structure results for six hydrogen bonded dimers, namely, NH3-NH3, H2O-H2O, HF-HF, H2O-NH3, HF-H2O, and HF-NH3, and validated its performance for extended parts of their potential energy surfaces, resulting in a mean absolute error ranging from 0.

Morphological Characteristics and Extracellular Matrix Abnormalities in Astrocytes Derived From iPSCs of Children With Alexander Disease.

Aims: Alexander disease (AxD) is a leukodystrophy caused by mutations in the astrocytic filament gene GFAP. There are currently no effective treatments for AxD. Previous studies have rarely established AxD models with the patient's original GFAP mutations.

TBC1D20 coordinates vesicle transport and actin remodeling to regulate ciliogenesis.

TBC1D20 deficiency causes Warburg Micro Syndrome in humans, characterized by multiple eye abnormalities, severe intellectual disability, and abnormal sexual development, but the molecular mechanisms remain unknown. Here, we identify TBC1D20 as a novel Rab11 GTPase-activating protein that coordinates vesicle transport and actin remodeling to regulate ciliogenesis. Depletion of TBC1D20 promotes Rab11 vesicle accumulation and actin deconstruction around the centrosome, facilitating the initiation of ciliogenesis even in cycling cells.

TP53 Mutations and PD-L1 Amplification in Vulvar Adenocarcinoma of the Intestinal Type: Insights From Whole Exome Sequencing of 2 Cases.

Vulvar adenocarcinoma of the intestinal type (VAIt) is a rare subtype of primary vulvar carcinoma, with ∼30 cases documented in the English literature. This study presents 2 new cases of HPV-independent VAIt with lymph node metastasis and discusses their clinical presentation, histopathologic features, and whole exome sequencing (WES) analysis. Both cases exhibited histologic features consistent with VAIt, including tubular, papillary, and mucinous carcinoma components.

CD20 and CD19 promote proliferation driven by the IgM-TLR9-L265P MyD88 complex.

The cancer driver mutation L265P MyD88 is found in approximately 30 % of cases in the activated B cell-like subgroup of diffuse large B cell-like lymphoma (ABC DLBCL). L265P MyD88 forms a complex with TLR9 and IgM, referred to as the My-T-BCR complex, to drive proliferation. We here show that the B cell surface molecules CD19 and CD20 enhance proliferation mediated by the My-T-BCR complex.

Adult hypophosphatasia presenting with recurrent acute joint pain.

Summary: Hypophosphatasia (HPP) is a genetic disorder due to pathological variants in ALPL, the gene encoding tissue-nonspecific alkaline phosphatase (ALP). HPP is typically associated with bone-related symptoms, such as bone deformity, fractures and bone pain in children, but can appear in adults with symptoms resembling arthritis. A 22-year-old male experienced repeated and severe sudden attacks of joint pain in the elbows and knees.

Has AlphaFold3 achieved success for RNA?

Predicting the 3D structure of RNA is a significant challenge despite ongoing advancements in the field. Although AlphaFold has successfully addressed this problem for proteins, RNA structure prediction raises difficulties due to the fundamental differences between proteins and RNA, which hinder its direct adaptation. The latest release of AlphaFold, AlphaFold3, has broadened its scope to include multiple different molecules such as DNA, ligands and RNA.

Pseudohypoparathyroidism type 1A presenting as short stature and congenital hypothyroidism.

Summary: Short stature is a common complaint among pediatric visits and the differential diagnosis is extensive. Although some variations in growth are normal, deviation from normal growth is often the first symptom of chronic disease in children. This is true for hormone abnormalities including growth hormone deficiency, hypothyroidism and glucocorticoid excess.
