Seminal Fluid Metabolomic Markers of Oligozoospermic Infertility in Humans.

Infertility affects 12-15% of couples worldwide, and male factors are the cause of nearly half of all cases. Studying seminal fluid composition could lead to additional diagnostic accuracy and a better understanding of the pathophysiology of male factor infertility. Metabolomics offers a new opportunity to evaluate biomarkers and better understand pathological mechanisms.

Triplet-primed PCR is more sensitive than southern blotting-long PCR for the diagnosis of myotonic dystrophy type1.

Genetic testing of myotonic dystrophy type 1 (DM1) is very important because it enables the diagnosis and indicates the severity of the disease. Mutation analysis is based on the detection of the number of CTG triplets in the 3' untranslated region of the myotonic dystrophy protein kinase (DMPK) gene. Sometimes it could be complicated by the presence of different patterns of repeat interruptions in the 5' and 3' ends of the expanded alleles recently described in about 3% to 5% of patients.

A new deletion in 5'-end of dystrophin gene removing M and P promoters and dystrophin muscle enhancers.

We describe a 3-year-old boy who, at age of 8 months, during investigations for upper respiratory tract infection was found to have an incidental grossly elevated CK of 20,000 UI/l. Investigations showed only mild calf hypertrophy and absent Gower's sign, normal cognitive function. Electromyography (EMG) showed myopathic features.

C329X in KRIT1 is a founder mutation among CCM patients in Sardinia.

Cerebral cavernous malformations (CCMs) are CNS vascular anomalies associated with seizures, headaches and hemorrhagic strokes and represent 10-20% of cerebral lesions. CCM is present in 0.1-0.
