EEG Functional Connectivity and Cognitive Variables in Premanifest and Manifest Huntington's Disease: EEG Low-Resolution Brain Electromagnetic Tomography (LORETA) Study.

Background: Scientific literature does not offer sufficient data on electroencephalography (EEG) functional connectivity and its correlations with clinical and cognitive features in premanifest and manifest HD.

Aim: This study tries to identify abnormal EEG patterns of functional connectivity, in conditions of "brain resting state" and correlations with motor decline and cognitive variable in Huntington's disease (HD), in premanifest and manifest phase, looking for a reliable marker measuring disease progression.

Method: This was an observational cross-sectional study; 105 subjects with age ≥18 years submitted to HD genetic test.

JNK is antagonized to ensure the correct number of interommatidial cells pattern the Drosophila retina.

Apoptosis is crucial during the morphogenesis of most organs and tissues, and is utilized for tissues to achieve their proper size, shape and patterning. Many signaling pathways contribute to the precise regulation of apoptosis. Here we show that Jun N-terminal Kinase (JNK) activity contributes to the coordinated removal of interommatidial cells via apoptosis in the Drosophila pupal retina.

Brief Report: Rethinking Data Collection for HIV Prevention Trials.

There is a strong push to conduct large-scale randomized controlled study designs in HIV prevention studies. In these randomized controlled studies, the primary research objective is typically to determine the treatment effect based on some biological outcome (eg, HIV infection). But many unused self-reported outcomes are also being collected.

[The use of echography and US-guided percutaneous puncture in addition to mammography for the detection of malignant breast tumors].

At present, mammography is the most effective means to detect breast cancers, especially in the early stages. However, it lacks sensitivity and specificity in women with dense breasts. Moreover, indeterminate lesions are often seen on mammograms, which should undergo further examination before surgery.

DNA repair investigations in nine Italian patients affected by trichothiodystrophy.

Trichothiodystrophy (TTD) is a rare autosomal recessive disorder characterized by brittle hair, mental and growth retardation, peculiar face, ichthyosis, and in 20% of the reported cases photosensitivity. Cellular photosensitivity due to the same genetic defect present in xeroderma pigmentosum group D (XP-D) has been described in several patients. Nine patients with clinical symptoms diagnostic for TTD have been identified in Italy to date.
