Predictors Associated with the Need for Open Reduction of Pediatric Supracondylar Humerus Fractures: A Meta-analysis of the Recent Literature.

Background: Supracondylar humerus (SCH) fractures are some of the most common fractures in pediatric patients with surgery typically consisting of either open or closed reduction with internal fixation. The aim of this meta-analysis was to identify patient, injury, and administrative factors that are associated with treating pediatric SCH fractures with open techniques.

Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, PubMed and CINAHL database searches were conducted for studies from 2010 to 2023 that made direct comparisons between open reduction and internal fixation (ORIF) and closed reduction and percutaneous pinning (CRPP) for treating SCH fractures in the pediatric population.

Aging AdipoR2-deficient mice are hyperactive with enlarged brains excessively rich in saturated fatty acids.

To investigate how the fatty acid composition of brain phospholipids influences brain-specific processes, we leveraged the AdipoR2 (adiponectin receptor 2) knockout mouse model in which the brain is enlarged, and cellular membranes are excessively rich in saturated fatty acids. Lipidomics analysis of brains at 2, 7, and 18 months of age showed that phosphatidylcholines, which make up about two-thirds of all cerebrum membrane lipids, contain a gross excess of saturated fatty acids in AdipoR2 knockout mice, and that this is mostly attributed to an excess palmitic acid (C16:0) at the expense of oleic acid (C18:1), consistent with a defect in fatty acid desaturation and elongation in the mutant. Specifically, there was a ~12% increase in the overall saturated fatty acid content within phosphatidylcholines and a ~30% increase in phosphatidylcholines containing two palmitic acids.

Pathology of Squamous Cell Carcinoma of the Penis: Back to Square One.

The landscape of squamous cell carcinoma of the penis (SCC-P) has undergone a significant transformation since the new World Health Organization classification of genitourinary cancers and recent European Association of Urology/American Association of Clinical Oncology guidelines. These changes emphasize the necessity to categorize SCC-P into 2 groups based on its association with human papillomavirus (HPV) infection. This shift has major implications, considering that prior knowledge was derived from a mix of both groups.

Offshore produced water treatment by a biofilm reactor on the seabed: The effect of temperature and matrix characteristics.

In many industrial processes a large amount of water with high salinity is co-produced whose treatment poses considerable challenges to the available technologies. The produced water (PW) from offshore operations is currently being discharged to sea without treatment for dissolved pollutants due to space limitations. A biofilter on the seabed adjacent to a production platform would negate all size restrictions, thus reducing the environmental impact of oil and gas production offshore.

Emerging roles of plant transcriptional gene silencing under heat.

Plants continuously endure unpredictable environmental fluctuations that upset their physiology, with stressful conditions negatively impacting yield and survival. As a contemporary threat of rapid progression, global warming has become one of the most menacing ecological challenges. Thus, understanding how plants integrate and respond to elevated temperatures is crucial for ensuring future crop productivity and furthering our knowledge of historical environmental acclimation and adaptation.

Gradual and synergistic correlation of tumor thickness and histological grade in penile invasive carcinomas.

Histological grade and depth of invasion are among the best outcome pathological predictors in penile cancer. The TNM system is based on a combination of both for some stages. It is assumed that high-grade and deep tumors carry the worst prognosis, and the opposite occurs with superficial and low-grade neoplasms.

Flipped classroom in neurophysiology: performance analysis of a system focusing on intrinsic students' motivation.

Teaching methodologies promoting active learning result in higher-order knowledge application, a desirable outcome in health disciplines like Physiology. Flipped-classroom (FC) promotes active learning and engagement in the classroom. Although specialized research keeps accumulating, the advantages of FC for improving academic outcome and ultimately patient care remain controversial and open to further analysis.

Evaluation of three formulations based on Polymorphic membrane protein D in mice infected with .

The significant impact of infections worldwide highlights the need to develop a prophylactic vaccine that elicits effective immunity and protects the host from the immunopathological effects of infection. The aim of this study was to evaluate a vaccine based on a fragment of the Polymorphic membrane protein D (FPmpD) of as an immunogen using a heterologous DNA prime-protein boost strategy in female mice Three different formulations were evaluated as protein boost: free recombinant FPmpD (rFPmpD) or rFPmpD formulated with a liposomal adjuvant alternatively supplemented with CpG or a cationic lipopeptide as immunostimulants. The three candidates induced an increase in the cervicovaginal and systemic titers of anti-rFPmpD antibodies in two strains of mice (BALB/c and C57BL/6), with no evidence of fertility alterations.

Insulin-degrading enzyme (IDE) as a modulator of microglial phenotypes in the context of Alzheimer's disease and brain aging.

The insulin-degrading enzyme (IDE) is an evolutionarily conserved zinc-dependent metallopeptidase highly expressed in the brain, where its specific functions remain poorly understood. Besides insulin, IDE is able to cleave many substrates in vitro, including amyloid beta peptides, making this enzyme a candidate pathophysiological link between Alzheimer's disease (AD) and type 2 diabetes (T2D). These antecedents led us to address the impact of IDE absence in hippocampus and olfactory bulb.

Canonical transcriptional gene silencing may contribute to long-term heat response and recovery through MOM1.

Plant canonical transcriptional gene silencing (TGS) is involved in epigenetic mechanisms that mediate genomic imprinting and the suppression of transposable elements (TEs). It has been recognised that long-term heat disrupts epigenetic silencing, with the ensuing activation of TEs. However, the physiological involvement of the TGS machinery under prolonged high temperatures has not yet been established.

Selection of a novel cell-internalizing RNA aptamer specific for CD22 antigen in B cell acute lymphoblastic leukemia.

Despite improvements in B cell acute lymphoblastic leukemia (B-ALL) treatment, a significant number of patients experience relapse of the disease, resulting in poor prognosis and high mortality. One of the drawbacks of current B-ALL treatments is the high toxicity associated with the non-specificity of chemotherapeutic drugs. Targeted therapy is an appealing strategy to treat B-ALL to mitigate these toxic off-target effects.

Transcriptomic and physiological shade avoidance responses in potato (Solanum tuberosum) plants.

Plants detect competitors in shaded environments by perceiving a reduction in photosynthetically active radiation (PAR) and the reduction between the red and far-red light (R:FR) ratio and blue photons. These light signals are detected by phytochromes and cryptochromes, which trigger shade avoidance responses such as shoot and petiole elongation and lead to increased susceptibility to pathogen attack. We studied morphological, anatomical, and photosynthesis differences in potato plants (Solanum tuberosum var.

Equid herpesvirus type 3 infection produces membrane-associated and secreted forms of glycoprotein G that are not required for efficient cell-to-cell spread of the virus in vitro.

The ORF 70 gene of equid alphaherpesvirus type 3 (EHV-3) encodes glycoprotein G (gG), which is conserved in the majority of alphaherpesviruses. This glycoprotein is located in the viral envelope and has the characteristic of being secreted into the culture medium after proteolytic processing. It modulates the antiviral immune response of the host by interacting with chemokines.

Dual role of Apolipoprotein D as long-term instructive factor and acute signal conditioning microglial secretory and phagocytic responses.

Microglial cells are recognized as very dynamic brain cells, screening the environment and sensitive to signals from all other cell types in health and disease. Apolipoprotein D (ApoD), a lipid-binding protein of the Lipocalin family, is required for nervous system optimal function and proper development and maintenance of key neural structures. ApoD has a cell and state-dependent expression in the healthy nervous system, and increases its expression upon aging, damage or neurodegeneration.

Penile squamous cell carcinoma exclusive to the shaft, with a proposal for a novel staging system.

Penile squamous cell carcinomas (SCC) originating in the shaft are rare. pT1/pT2 categories in the American Joint Committee on Cancer (AJCC) staging manual (8th edition) are poorly defined for SCCs arising in the dorsal shaft as anatomic structures differ between the glans and dorsal shaft (corpus spongiosum vs dartos/Buck's fascia, respectively). We reviewed six penile SCC cases exclusive to the shaft, an unusual presentation, identified amongst 120 patients treated with penectomy.

Penile intraepithelial neoplasia: Distribution of subtypes, HPV genotypes and p16 in 84 international cases.

There are few pathologic or molecular studies of penile precancerous lesions, and the majority refers to lesions associated with invasive carcinomas. Penile Intraepithelial Neoplasia (PeIN) is classified in two morphologically and distinctive molecular groups, non-HPV and HPV-related with special subtypes. The primary purpose of this international series was to classify PeIN morphologically, detect HPV genotypes and determine their distribution according to PeIN subtypes.

The dual pathogenesis of penile neoplasia: The heterogeneous morphology of human papillomavirus-related tumors.

Objective: Penile neoplasia, usually of squamous histogenesis, is currently classified into human papillomavirus (HPV)-related or -dependent and non-HPV-related or -independent. There are distinct morphological differences among the two groups. New research studies on penile cancer from Northern countries showed that the presence of HPV is correlated with a better prognosis than virus negative people, while studies in Southern countries had not confirmed, perhaps due to differences in staging or treatment.

Rearranged Endogenized Plant Pararetroviruses as Evidence of Heritable RNA-based Immunity.

Eukaryotic genomics frequently revealed historical spontaneous endogenization events of external invading nucleic acids, such as viral elements. In plants, an extensive occurrence of endogenous plant pararetroviruses (EPRVs) is usually believed to endow hosts with an additional layer of internal suppressive weaponry. However, an actual demonstration of this activity remains speculative.

Functional analysis of polymorphisms in collected in Patagonia.

shows a wide range of natural genetic variation in light responses. Shade avoidance syndrome is a strategy of major adaptive significance that includes seed germination, elongation of vegetative structures, leaf hyponasty, and acceleration of flowering. Previously, we found that the southernmost Arabidopsis accession, collected in the south of Patagonia (Pat), is hyposensitive to light and displays a reduced response to shade light.

Partial Superior Capsular Reconstruction to Augment Arthroscopic Repair of Massive Rotator Cuff Tears Using Autogenous Biceps Tendon: Effect on Retear Rate.

Background: Massive rotator cuff tears have a high incidence of postoperative retear that can reach 90%. It is still unclear which intervention may reduce the incidence of retear and improve the functional and clinical outcomes.

Purpose/hypothesis: The purpose of this study was to investigate the clinical and structural outcomes at 2 years after repair of reparable massive rotator cuff tears with and without the use of partial superior capsular reconstruction (pSCR), using the autologous long head of the biceps tendon (LHBT) as a graft.

Extraction of a fractured pacemaker lead in the left bundle branch area using a snare via a femoral approach.

We present the first reported case of extraction of a ventricular lead placed in the left bundle branch area with a double-loop design snare via the femoral approach without any complication. It was a 4-month-old lead whose extraction was not possible only with a conventional stylet via an implant vein approach, so we want to show that complete procedural success is possible.

Dual role of specific promoter tandem repeats integrating epigenetic silencing with heat response.

Satellites are ubiquitous noncoding tandemly repeated sequences, yet knowledge about their biological relevance is still scarce. In plants, the few described cases point to roles in heterochromatin biology and gene regulation; however, a direct link to plant stress responses is yet to be uncovered. We present evidence that particular non-centromere tandem repeats may display a central regulatory role in the intersection between epigenetic silencing and gene expression in dynamic environments.
