Gene Therapy Approach for Treatment of Obese Agouti Mice.

Obesity is a significant metabolic disorder associated with excessive fat accumulation and insulin resistance. In this study, we explored a gene therapy approach to treat obesity in agouti mice using adeno-associated viruses (AAVs) carrying PRDM16, FoxP4, or Follistatin (FST) genes, which are known to promote the browning of white adipose tissue. Mice treated with AAVs encoding PRDM16, FoxP4, or FST genes showed a reduction in body weight (10-14%) within the first three weeks after administration, compared to the control groups.

Dual Adeno-Associated Virus 9 with Codon-Optimized DYSF Gene Promotes In Vivo Muscle Regeneration and May Decrease Inflammatory Response in Limb Girdle Muscular Dystrophy Type R2.

Dysferlinopathy treatment is an active area of investigation. Gene therapy is one potential approach. We studied muscle regeneration and inflammatory response after injection of an AAV-9 with a codon-optimized DYSF gene.

Raman spectroscopy in chronic heart failure diagnosis based on human skin analysis.

This work aims at studying Raman spectroscopy in combination with chemometrics as an alternative fast noninvasive method to detect chronic heart failure (CHF) cases. Optical analysis is focused on the changes in the spectral features associated with the biochemical composition changes of skin tissues. A portable spectroscopy setup with the 785 nm excitation wavelength was used to record skin Raman features.

Analyzing the serum of hemodialysis patients with end-stage chronic kidney disease by means of the combination of SERS and machine learning.

The aim of this paper is a multivariate analysis of SERS characteristics of serum in hemodialysis patients, which includes constructing classification models (PLS-DA, CNN) by the presence/absence of end-stage chronic kidney disease (CKD) with dialysis and determining the most informative spectral bands for identifying dialysis patients by variable importance distribution. We found the spectral bands that are informative for detecting the hemodialysis patients: the 641 cm, 724 cm, 1094 cm and 1393 cm bands are associated with the degree of kidney function inhibition; and the 1001 cm band is able to demonstrate the distinctive features of hemodialysis patients with end-stage CKD.

[POEMS-syndrome: diagnostic difficulties].

POEMS syndrome is a rare paraneoplastic syndrome whose name is an acronym formed from the initial letters of the names of the symptoms originally used to determine it: polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes. Due to the rarity of the disease and the small number of cases described in the literature, its diagnosis is difficult. The average time from onset of symptoms to diagnosis is 18 months.
