Andrologia, 2016 Nonobstructive azoospermia is caused in up to 10% by microdeletions of the Y chromosome in the azoospermia factor (AZF) region, which is divided into three nonoverlapping areas (AZFa, AZFb and AZFc).

How I Do It: A Novel Case Series of Office‐Based Laser Complete Excision of Vocal Fold Cysts
The Laryngoscope, EarlyView.Office‐based complete excision of vocal fold cysts using Trublue laser via transnasal flexible endoscopy is a technically feasible alternative to conventional marsupialization, enabling en bloc removal under local anesthesia with excellent procedural tolerability.

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research
Mass Spectrometry Reviews, EarlyView.Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

Mass Spectrometry Reviews, EarlyView.ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

The Journal of Pathology, EarlyView.Abstract Recently, we suggested the combination of chemotherapy and P2RX4 inhibition as a promising novel therapeutic approach for P2RX4‐expressing epithelial tumors to prevent paracrine resistance. Here, we aimed to assess whether determining P2RX4 expression status in colorectal and pancreatic cancer patients would allow stratification of potentially

Andrology, EarlyView.ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...

Can Hormonal Therapy Improve the Outcomes of mTESE in Patients With Non‐Obstructive Azoospermia?
Andrology, EarlyView.ABSTRACT Background Non‐obstructive azoospermia (NOA) represents the most severe form of male infertility. Hypogonadism is common in NOA patients, and normal testosterone (T) levels are considered essential for spermatogenesis. Fertility‐preserving hormonal therapy (FpHT) has been proposed to optimize hormonal milieu and improve sperm retrieval rates ...

Andrology, EarlyView.ABSTRACT Background The Klinefelter syndrome is a common genetic cause of male infertility, and testicular sperm extraction (TESE) enables sperm retrieval in a subset of affected patients. However, predicting TESE success remains challenging due to the heterogeneous clinical and endocrinological presentation of the Klinefelter syndrome.

Cancer Science, EarlyView.Multi‐region sequencing of 57 BRCA1‐associated breast cancers identified TP53 as the dominant initial driver, defining a triple‐negative subgroup with biallelic BRCA1 loss and elevated genomic instability. TP53 truncating mutations were enriched in BRCA1 carriers and linked to reduced HRD, EMT activation, and a trend toward worse survival.

Spatially resolved mapping of histones reveals selective neuronal response in Rett syndrome
The FEBS Journal, EarlyView.Loss of Mecp2 function is associated with Rett syndrome (RTT). MeCP2 regulates chromatin, yet its influence on histone composition and dynamics is unclear. Combining MALDI‐MSI with LCM–LC–MS/MS, we mapped histone proteoforms across the dentate gyrus, cornu ammonis, and cerebellum in two mouse models of RTT.
