Interplay between tobacco curly shoot virus vsiRNA24 and triosephosphate isomerase: implications for Nicotiana benthamiana viral defense.

Virus-derived small interfering RNAs (vsiRNAs) play an important role in viral infection by regulating the expression of host genes. At present, research on the regulation of plant primary metabolic pathways by vsiRNAs is very limited. TvsiRNA24 derived from tobacco curly shoot virus (TbCSV) was amplified by reverse transcription polymerase chain reaction, and its target gene NbTPI (triosephosphate isomerase) was verified using reverse transcription quantitative polymerase chain reaction and GFP fluorescence observation.

Ethylene response transcription factor 5 (ERF5) enhances defense against tobacco curly shoot virus and associated betasatellite (TbCSV/TbCSB) in Nicotiana benthamiana.

Begomovirus/betasatellite disease complex significantly threatens global crop production. Identifying potential plant antiviral genes is crucial for disease control. Nicotiana benthamiana is susceptible to viruses and contains 266 ethylene response transcription factors (ERFs).

Se-Methylselenocysteine Ameliorates DEHP-Induced Ferroptosis in Testicular Sertoli Cells via the Nrf2/GPX4 Axis.

Di (2-ethylhexyl) phthalate (DEHP) is an important plasticizer in industrial production, and its toxic effects on testes are widely recognized. Se-methylselenocysteine (SMC) is a major selenium compound found in selenium-rich plants, which possesses unique biological properties such as antioxidants. However, the effect of SMC on DEHP-induced testicular injury and the specific mechanism remains unknown.

The TATA-box binding protein-associated factor TAF12b facilitates the degradation of type B response regulators to negatively regulate cytokinin signaling.

Cytokinins (CKs) are one of the important classes of plant hormones essential for plant growth and development. TATA-box binding protein-associated factor 12b (TAF12b) is involved in CK signaling, but its molecular and biochemical mechanisms are not fully understood. In this study, TAF12b of Nicotiana benthamiana (NbTAF12b) was found to mediate the CK response by directly interacting with type B response regulators (B-RRs), positive regulators of CK signaling, and inhibiting their transcriptional activities.

Sirt1 m6A modification-evoked Leydig cell senescence promotes Cd-induced testosterone decline.

Diminished testosterone levels have been documented as a key factor in numerous male health disorders. Both human and animal studies have consistently demonstrated that cadmium (Cd), a pervasive environmental heavy metal, results in decreased testosterone levels. However, the exact mechanism through which Cd interferes with testosterone synthesis remains incompletely elucidated.

Activation of lipophagy ameliorates cadmium-induced neural tube defects via reducing low density lipoprotein cholesterol levels in mouse placentas.

Neural tube defects (NTDs) represent a prevalent and severe category of congenital anomalies in humans. Cadmium (Cd) is an environmental teratogen known to cause fetal NTDs. However, its underlying mechanisms remain elusive.

m6A-methylated Lonp1 drives mitochondrial proteostasis stress to induce testicular pyroptosis upon environmental cadmium exposure.

Cadmium (Cd) is a widely distributed typical environmental pollutant and one of the most toxic heavy metals. It is well-known that environmental Cd causes testicular damage by inducing classic types of cell death such as cell apoptosis and necrosis. However, as a new type of cell death, the role and mechanism of pyroptosis in Cd-induced testicular injury remain unclear.

A long-term prognosis study of human USP8-mutated ACTH-secreting pituitary neuroendocrine tumours.

Objective: Somatic variants in the ubiquitin-specific protease 8 (USP8) gene are the most common genetic cause of Cushing disease. We aimed to explore the relationship between clinical outcomes and USP8 status in a single centre.

Design, Patients And Measurements: We investigated the USP8 status in 48 patients with pituitary corticotroph tumours.

NBR1-dependent autophagy activation protects against environmental cadmium-evoked placental trophoblast senescence.

Cadmium (Cd), a well-established developmental toxicant, accumulates in the placentae and disrupts its structure and function. Population study found adverse pregnancy outcomes caused by environmental Cd exposure associated with cell senescence. However, the role of autophagy activation in Cd-induced placental cell senescence and its reciprocal mechanisms are unknown.

Environmental cadmium inhibits testicular testosterone synthesis via Parkin-dependent MFN1 degradation.

Low testosterone (T) levels are associated with many common diseases, such as obesity, male infertility, depression, and cardiovascular disease. It is well known that environmental cadmium (Cd) exposure can induce T decline, but the exact mechanism remains unclear. We established a murine model in which Cd exposure induced testicular T decline.

Transurethral surgical treatment for benign prostatic hyperplasia with detrusor underactivity: a systematic review and meta-analysis.

Background: The efficacy of surgical treatment for benign prostatic hyperplasia (BPH) patients with detrusor underactivity (DU) remains controversial.

Methods: To summarize relevant evidence, three databases (PubMed, Embase, and Web of Science) were searched from database inception to May 1, 2023. Transurethral surgical treatment modalities include transurethral prostatectomy (TURP), photoselective vaporization of the prostate (PVP), and transurethral incision of the prostate (TUIP).

Maternal prednisone exposure during pregnancy elevates susceptibility to osteoporosis in female offspring: The role of mitophagy/FNDC5 alteration in skeletal muscle.

Maternal exposure to glucocorticoids has been associated with adverse outcomes in offspring. However, the consequences and mechanisms of gestational exposure to prednisone on susceptibility to osteoporosis in the offspring remain unclear. Here, we found that gestational prednisone exposure enhanced susceptibility to osteoporosis in adult mouse offspring.

Cytokine IL-5 and HGF: combined prediction of non-/low immune response to hepatitis B vaccination at birth in infants born to HBsAg-positive mothers.

Background: The immune response to hepatitis B vaccine may be influenced by numerous factors, and patients with non/low response re-exposed to hepatitis B virus remain susceptible. Thus, a better understanding of the underlying mechanisms of non/low immune response in infants born to Hepatitis B surface antigen (HBsAg)-positive mothers is essential.

Methods: 100 infants born to HBsAg-positive mothers from 2015 to 2020 were enrolled in the study, further divided into the non/low response group (n=13) and the moderate strong response group (n=87) based on the quantification of hepatitis B surface antibody at 12 months of age.

Preliminary analysis of stimulation parameters for sacral neuromodulation in different indications: a multicenter retrospective cohort study from China.

Background: Sacral neuromodulation (SNM) is an effective approach for treating lower urinary tract dysfunction (LUTD), and stimulation programming is essential for successful treatment. However, research on SNM programming for various indications is limited. Thus, the authors aimed to determine whether there were differences in the stimulation parameters for different SNM indications and the appropriate programming recommendations.

High expression of BCAT1 sensitizes AML cells to PARP inhibitor by suppressing DNA damage response.

Previous evidence has confirmed that branched-chain aminotransferase-1 (BCAT1), a key enzyme governing branched-chain amino acid (BCAA) metabolism, has a role in cancer aggression partly by restricting αKG levels and inhibiting the activities of the αKG-dependent enzyme family. The oncogenic role of BCAT1, however, was not fully elucidated in acute myeloid leukemia (AML). In this study, we investigated the clinical significance and biological insight of BCAT1 in AML.

A Laparoscopically Compatible Rapid-Adhesion Bioadhesive for Asymmetric Adhesion, Non-Pressing Hemostasis, and Seamless Seal.

Bioadhesive hydrogels offer unprecedented opportunities in hemostatic agents and tissue sealing; however, the application of existing bioadhesive hydrogels through narrow spaces to achieve strong adhesion in fluid-rich physiological environments is challenged either by undesired indiscriminate adhesion or weak wet tissue adhesion. Here, a laparoscopically compatible asymmetric adhesive hydrogel (aAH) composed of sprayable adhesive hydrogel powders and injectable anti-adhesive glue is proposed for hemostasis and to seal the bloody tissues in a non-pressing way, allowing for preventing postoperative adhesion. The powders can seed on the irregular bloody wound to rapidly absorb interfacial fluid, crosslink, and form an adhesive hydrogel to hemostatic seal (blood clotting time and tissue sealing in 10 s, ≈200 mm Hg of burst pressure in sealed porcine tissues).

Repressing HIF-1α-induced HDAC9 contributes to the synergistic effect of venetoclax and MENIN inhibitor in KMT2Ar AML.

KMT2A-rearranged acute myeloid leukemia (KMT2Ar-AML) is an aggressive subtype of AML with poor response and prognosis. KMT2Ar-AML has been demonstrated to be sensitive to BCL2 inhibitor venetoclax (VEN), but these patients are unable to benefit from current VEN-based regimen (VEN plus azacitidine or low dose-cytarabine), so a novel and KMT2A rearrangement-specific targeting partner is required, and MENIN inhibitor (MEN1i) is a promising one. Herein, we investigated the effect and mechanism of VEN plus MEN1i in KMT2Ar-AML.

Bladder Replacement Therapy.

The bladder, as a vital organ of the urinary system, facilitates urine storage and micturition. The bladder can store urine under low pressure, sense volume changes, and coordinate with the urethral sphincter to ensure autonomous and efficient urination and bladder emptying. However, irreversible bladder damage may result from various conditions, such as nerve injuries, aging, or metabolic syndrome, compromising its normal physiological functions and necessitating various interventions for anatomical and functional bladder replacements.
