Black Chokeberry () Juice Supplementation Affects Age-Related Myocardial Remodeling in Rats.

Background: Cardiac aging is associated with myocardial remodeling and reduced angiogenesis. Counteracting these changes with natural products is a preventive strategy with great potential. The aim of this study was to evaluate the effect of fruit juice (AMJ) supplementation on age-related myocardial remodeling in aged rat hearts.

Strategies in Surgical Salvage: Navigating a Chest Wall Sarcoma Emergency.

Soft tissue sarcomas arising from the chest wall are an extremely rare entity. They are classified as mesenchymal tumors of varying aggression. It is this unpredictable behavior that makes them an unexpected hurdle even for experienced surgeons.

Analysis and evaluation of correlation between DNA polymorphism in the genes MTHFR, PAI-1 and serum creatinine, creatinine clearance and albumin/creatinine ratio in morning urine of patients with type 2 diabetes mellitus and diabetic nephropathy.

Diabetic nephropathy is a major microangiopathic complication of type 2 diabetes and a leading cause of chronic kidney disease (CKD).

Rhythm and conduction complications after COVID-19 infection in physiological hypertrophy of myocardium (athlete's heart).

The term 'athletic heart syndrome' (AHS) is used to describe specific circulatory and morphological changes in individuals who participate in sports competitions. The syndrome is characterized by normal cardiac function and reversible myocardial remodelling.The incidence and severity of the post-COVID-19 cardiac pathology in active athletes are so far unclear.

Catecholamine-induced cardiomyopathy - a clinical case.

A 27-year-old patient presented with a 3-month history of episodic headaches and persistently rising blood pressure (up to 240/120). The clinical, laboratory, and instrumental findings (episodes of severe hypertension, increased levels of metanephrine in urine, and MRI showing a mass of 5.1×5.

Case Report: Difficulties in the Treatment of a 12-Year-Old Patient With Homozygous Familial Hypercholesterolemia, Compound Heterozygous Form - 5 Years Follow-Up.

The literature review we conducted reveals the limited use of proprotein convertase subtilisin/kexin type 9-inhibitors (PCSK9i) in children with familial hypercholesterolemia (FH). In 2015, a 10-year-old boy presented with round, xanthochromic lesions on his right knee and elbow. The values of total and LDL-cholesterol (LDL-C)-18 and 15 mmol/l, respectively-along with normal triglycerides and HDL-cholesterol (HDL-C) confirmed the lesions were xanthomas.

Black Chokeberry () Functional Beverages Increase HDL-Cholesterol Levels in Aging Rats.

Plant-based foods rich in phenolic phytochemicals are among the promising strategies to counteract age-related changes in lipid profile. (AM) fruits are a rich source of phenolic compounds possessing lipid-modulating effects. The present study investigated the effect of 3-month supplementation of AM-based functional beverages on the lipid profile of healthy aging rats.

Purification, characterization, and immunogenicity of the refolded ectodomain of the Plasmodium falciparum apical membrane antigen 1 expressed in Escherichia coli.

The apical membrane antigen 1 (AMA1) has emerged as a promising vaccine candidate against malaria. Advanced evaluation of its protective efficacy in humans requires the production of highly purified and correctly folded protein. We describe here a process for the expression, fermentation, refolding, and purification of the recombinant ectodomain of AMA1 (amino acids 83(Gly) to 531(Glu)) of Plasmodium falciparum (3D7) produced in Escherichia coli.

Two-step chromatographic purification of recombinant Plasmodium falciparum circumsporozoite protein from Escherichia coli.

The Plasmodium falciparum circumsporozoite (PfCS) protein (aa 19-405) has been cloned and expressed in E. coli. The protein was purified in a two-step process that was rapid and reproducible.

Synthetic oligodeoxynucleotides containing CpG motifs enhance immunogenicity of a peptide malaria vaccine in Aotus monkeys.

Synthetic peptide and recombinant protein vaccines are optimally immunogenic when delivered with an effective adjuvant. Candidate vaccines currently insufficiently immunogenic may induce a protective immunity if they could be delivered with more effective adjuvants. For example, immunogens that induce promising responses when administered to mice with complete and incomplete Freund's adjuvants perform less well in primate animal models where complete Freund's adjuvant is not used.

Immunogenicity of Plasmodium falciparum circumsporozoite protein multiple antigen peptide vaccine formulated with different adjuvants.

Only low antibody levels were obtained from vaccinating human volunteers with single-chain peptide from the Plasmodium falciparum circumsporozoite protein (PfCSP). This resulted in modest protection against sporozoite challenge. In addition, HLA restriction limits the probability of synthesis of a vaccine effective for a diverse population.

Inactivated whole-virus vaccine derived from a proviral DNA clone of simian immunodeficiency virus induces high levels of neutralizing antibodies and confers protection against heterologous challenge.

We tested the ability of macaques vaccinated with inactivated whole simian immunodeficiency virus (SIV) to resist challenge with either homologous or heterologous cell-free uncloned SIV administered by the intravenous route. The vaccine virus was derived from a proviral DNA clone and thus was considered genetically homogeneous. Sixteen macaques received either hepatitis B surface antigen (n = 6) or the inactivated whole-SIV vaccine (n = 10) at weeks 0, 4, and 49 of the study.

The genetic fate of molecularly cloned simian immunodeficiency virus in experimentally infected macaques.

We have examined genetic variation of the simian immunodeficiency virus (SIV) in four macaques inoculated with virions derived from molecular clones of proviral DNA. Our data demonstrated that the SIV genome is capable of rapid and extensive genetic variation. This variation was especially large in the env gene, where nucleotide substitution frequencies were as high as 10(-1)/site/year.
