Epigenetics of nonobstructive azoospermia

Asian Journal of Andrology
Nonobstructive azoospermia (NOA) is a severe and heterogeneous form of male factor infertility caused by dysfunction of spermatogenesis. Although various factors are well defined in the disruption of spermatogenesis, not all aspects due to the ...

The Incremental Prognostic Value of Hyperemic Coronary Flow Velocity in Patients with Angina and Nonobstructive Coronary Artery Disease. [PDF]

MedComm (2020)
Patients were first split by CFVR (≥ 2.5 vs. < 2.5). Among those with CFVR < 2.5, peak hyperemic CFV (hCFV) further defined Group B (> 0.44 m/s) and Group C (≤ 0.44 m/s). This hCFV‐guided split identified the ceiling of risk: Group C showed the highest MACE incidence, while Group B had substantially lower risk, consistent with pseudo‐low CFVR driven by

A novel stepwise micro-TESE approach in non obstructive azoospermia [PDF]

, 2016
Background: The purpose of the study was to investigate whether micro-TESE can improve sperm retrieval rate (SRR) compared to conventional single TESE biopsy on the same testicle or to contralateral multiple TESE, by employing a novel stepwise micro ...

Nonobstructive Bilateral Hydronephrosis & Hydroureter from Nephrogenic Diabetes Insipidus with a Novel Mutation of AQP2 Gene (p.A123G) [PDF]

Childhood Kidney Diseases, 2016
Nephrogenic diabetes insipidus (NDI) can cause nonobstructive hydronephrosis. Congenital NDI (CNDI) is caused by a genetic mutation. This case report presents a 12-year-old girl who was incidentally diagnosed with nonobstructive hydronephrosis due to NDI

Coronary CT Angiography and 5-Year Risk of Myocardial Infarction. [PDF]

, 2018
BACKGROUND: Although coronary computed tomographic angiography (CTA) improves diagnostic certainty in the assessment of patients with stable chest pain, its effect on 5-year clinical outcomes is unknown.

Hypertensive nonobstructive hydrocephalus as main magnetic resonance imaging feature in a dog with disseminated choroid plexus carcinomatosis

Journal of Veterinary Internal Medicine, 2023
Obstructive or nonobstructive hypertensive hydrocephalus is reported in choroid plexus tumors. Choroid plexus tumors typically present as T2‐weighted hyperintense intraventricular masses with occasional cerebrospinal fluid‐drop metastasis.

Development of a predictive model for increasing sperm retrieval success by microdissection testicular sperm extraction in patients with nonobstructive azoospermia

Asian Journal of Andrology, 2023
Microdissection testicular sperm extraction (micro-TESE) is widely used to treat nonobstructive azoospermia. However, a good prediction model is required to anticipate a successful sperm retrieval rate before performing micro-TESE.
