GenisteinSupplementation, CardiacFunction in Postmenopausal-Women with MetabolicSyndrome: Results from Pilot-Strain-Echo Study
Genistein, a soy-derived isoflavone, may improve cardiovascular risk profile in postmenopausal women with metabolic syndrome (MetS), but few literature data on its cardiac effects in humans are available. The aim of this sub-study of a randomized double-blind case-control study was to analyze the effect on cardiac function of one-year genistein dietary supplementation in 22 post-menopausal patients with MetS. Participants received 54 mg/day of genistein (n = 11) or placebo (n = 11) in combination with a Mediterranean-style diet and regular exercise. Left ventricular (LV) systolic function was assessed as the primary endpoint, according to conventional and strain-echocardiography measurements. Also, left atrial (LA) morphofunctional indices were investigated at baseline and at the final visit. Results were expressed as median with interquartile range (IQ). A significant improvement of LV ejection fraction (20.3 (IQ 12.5) vs. -1.67 (IQ 24.8); p = 0.040)), and LA area fractional change (11.1 (IQ 22.6) vs. 2.8 (9.5); p = 0.034)) were observed in genistein patients compared to the controls, following 12 months of treatment. In addition, body surface area indexed LA systolic volume and peak LA longitudinal strain significantly changed from basal to the end of the study in genistein-treated patients. One-year supplementation with 54 mg/day of pure genistein improved both LV ejection fraction and LA remodeling and function in postmenopausal women with MetS.

Biopolymer Based Prodrugs as Potential Antineoplastic Therapy
Cancer represents a major public health issue, a substantial economic issue, and a burden for society. Limited by numerous disadvantages, conventional chemotherapy is being replaced by new strategies targeting tumor cells. In this context, therapies based on biopolymer prodrug systems represent a promising alternative for improving the pharmacokinetic and pharmacologic properties of drugs and reducing their toxicity. The polymer-directed enzyme prodrug therapy is based on tumor cell targeting and release of the drug using polymer–drug and polymer–enzyme conjugates. In addition, current trends are oriented towards natural sources. They are biocompatible, biodegradable, and represent a valuable and renewable source. Drug–polymer conjugates based on natural polymers such as chitosan (CTS), hyaluronic acid (HA), dextran (DEX), pullulan (PL), silk fibroin (SF), centyrins (CTR), heparin (HEP), and polysaccharides from Auricularia auricula (AAP) are presented.

Pharmacology of Biosimilars
Testing in animals is an old routine used for new drugs to avoid serious toxicity to humans. However, biological drugs may not always show a pharmacologic response in animal species; thus, the toxicity is an extension of the pharmacological response for biological drugs. Clinical pharmacology comparisons comprise the most relevant testing to support the biosimilarity of a biosimilar candidate. When a novel drug is developed, PK/PD testing is carried out on many volunteers to understand the diversity of disposition in terms of gender, age, and genetic distribution.

BPSD and Antipsychotics
Behavioral and psychological symptoms (BPSD) frequently occur during the disease progression; to treat agitation, aggressiveness, delusions and hallucinations, the use of antipsychotic drugs should be limited, due to their safety issues.

Diabetic Retinopathy Treatment
Diabetic retinopathy (DR) is one of the leading matters of vision-loss globally. Even though there have been extensive efforts to reduce vision loss, the prevalence of DR is still uprising. There are several pharmacological and surgical therapies currently used in clinics, but none of them has not been used as effective therapies at the early stage of DR.

Extracellular Vesicles in Lung Disease
The use of MSC-derived EVs as a potential therapy for lung disease is a fairly young but rapidly growing field, with current research covering a wide variety of lung diseases. The majority of the current research evaluating the therapeutic potential of EVs has been performed in in vitro or pre-clinical animal model systems. This review will describe current published research using EVs as a potential therapy for acute lung injury/acute respiratory distress syndrome (ALI/ARDS), bronchopulmonary dysplasia (BPD), idiopathic pulmonary fibrosis (IPF), pulmonary arterial hypertension (PAH), asthma, and silicosis.

Bacteriophage-Delivering Hydrogels
Hydrogels are non-toxic polymeric materials exhibiting three-dimensional networks along with their hydrophilic characteristics playing an essential role in containing large water content, which serves as a biocompatible environment suited for formulation and delivery of bacteriophages.

Oral Bioavailability and Regulatory Aspects
Oral bioavailability refers to the extent a substance or drug becomes completely available to systemic circulation or to its intended biological destination(s) via the oral route. High oral bioavailability reduces the amount of a drug necessary to achieve a desired pharmacological effect, therefore reducing the risk of side-effects and toxicity. Low oral bioavailability results in low efficacy and is a major reason for drug candidates failing to reach the market. Hence, oral bioavailability is one of the most important properties in drug design and development.

Anticancer Potential of Piper nigrum
Current anticancer therapy suffers from several limitations, including lack of selectivity and multidrug resistance. Natural products represent an excellent opportunity for the identification of new therapeutic options due to their safety, low toxicity, and general availability. Piper nigrum is one of the most popular species in the world, with growing fame as a source of bioactive molecules with pharmacological properties. Undeniable anticancer properties are reportetd for different Piper nigrum constituents, such as its main alkaloid piperine.

NLR in Allergic Diseases
Our understanding on the immunological roles of pathogen recognition in innate immunity has vastly increased over the past 20 years. Nucleotide-binding oligomerization domain (NOD)-like receptors (NLR) are cytosolic pattern recognition receptors (PRR) that are responsible for sensing microbial motifs and endogenous damage signals in mammalian cytosol for immune surveillance and host defense.
