Berberine in Diabetes and Related Complications Treatment
Berberine (BBR) is an isoquinoline alkaloid that can be extracted from herbs such as Coptis, Phellodendron, and Berberis. BBR has been widely used as a folk medicine to treat various disorders. It is a multi-target drug with multiple mechanisms. Studies have shown that it has antioxidant and anti-inflammatory properties and can also adjust intestinal microbial flora.

Flavonoids as CYP3A4 Inhibitors In Vitro
CYP enzymes are a group of heme-containing enzymes that play important roles in the metabolism of many drugs and other xenobiotics. They are located in the endoplasmic reticulum of cells throughout the body, but they are most abundant in the liver.

Characteristics of Mucosal Layer in Gastrointestinal Tract
The main constituents of mucus are water (90–95%), electrolytes, lipids (1–2%), and proteins. Owing to the presence of mucin, a large complex glycosylated protein, mucus can form mesh-like structured viscous gel layers on various mucosal tissues, such as the gastrointestinal (GI) tract, eyes, nose, and respiratory tract. In the GI tract, the mucus layer on the surface of the epithelial membrane can act as a smart physiological barrier not only for foreign substances with harmful potential and pathogens but also for orally dosed drugs. For effective and sufficient oral drug delivery, avoiding protective mechanisms and/or even turning barrier mechanisms should be considered. Therefore, several strategies have been developed to control the diffusive properties of drug nanoparticles within the mucus layer, including the mucopenetration and mucoadhesion of NCs.

Novel Pharmacological Targets of Post-Traumatic Stress Disorders
Post-traumatic stress disorder (PTSD) is a psychopathological condition with a heterogeneous clinical picture that is complex and challenging to treat. Its multifaceted pathophysiology still remains an unresolved question and certainly contributes to this issue. The pharmacological treatment of PTSD is mainly empirical and centered on the serotonergic system. Since the therapeutic response to prescribed drugs targeting single symptoms is generally inconsistent, there is an urgent need for novel pathogenetic hypotheses, including different mediators and pathways.

Current Application of DNSPEs in Drug Delivery
A drug nanocrystal self-stabilized Pickering emulsion (DNSPE) is a novel Pickering emulsion with drug nanocrystals as the stabilizer. As a promising drug delivery system, DNSPEs have attracted increasing attention due to their high drug loading capacity and ability to reduce potential safety hazards posed by surfactants or specific solid particles.

Medical and Non-Medical USA Opioid Crisis
Drug overdose deaths in the USA rose from 16,849 in 1999 to nearly 110,000—of which an estimated 75,000 involved opioids—in 2022. On a yearly basis, the opioid casualty rate is higher than the combined number of victims of firearm violence and car accidents. The COVID-19 epidemic might have helped to worsen the addiction crisis in the USA by stimulating drug use among adolescents and diverting national attention to yet another public health crisis. So far, the failure to effectively respond to the opioid crisis is due to the gap between narcotic product regulation, regulation of marketing practices and the rise of a corporate-dominated health care system.

Second-Generation Lipophosphonoxins and Their Applications
Lipophosphonoxins (LPPOs) represent a new group of membrane-targeting antibiotics. Three generations of LPPOs have been described: First-generation LPPOs, second-generation LPPOs, and LEGO-LPPOs. All three generations have a similar mode of bactericidal action of targeting and disrupting the bacterial cytoplasmic membrane of prokaryotic cells, with limited effect on eukaryotic cells. Second-generation LPPOs broaden the antibiotic effect also against Gram-negative bacteria. However, both first- and second-generation LPPOs lose their antibacterial activity in the presence of serum albumin. Second-generation LPPOs have been studied as antimicrobial additives in bone cement and as nanofiber dressing components in the treatment of wound infections in mice.

Development and Regulatory Approval of Biosimilars
Biological therapies have transformed high-burden treatments. As the patent and exclusivity period for biological medicines draws to a close, there is a possibility for the development and authorization of biosimilars. These products boast comparable levels of safety, quality, and effectiveness to their precursor reference products. Biosimilars, although similar to reference products, are not identical copies and should not be considered generic substitutes for the original. Their development and evaluation involve a rigorous step-by-step process that includes analytical, functional, and nonclinical evaluations and clinical trials. Clinical studies conducted for biosimilars aim to establish similar efficacy, safety, and immunogenicity, rather than demonstrating a clinical benefit, as with the reference product.

Multicomponent Mixtures and Single Compounds from
Lentinula edodes
Apart from the isolation of single substances, complexly composed products, so-called multicomponent mixtures (more than one constituent substances, MOCSs), are obtained from the natural materials. A multicomponent mixture contains numerous individual constituents with different functionalities. By using the example of Lentinula edodes (Berk.) Pegler, shiitake, it is shown that this is the case not only for plants but also for medicinal mushrooms. Lentinan, a polysaccharide isolated from the mycelium, is used as a single compound as part of an integrated tumor therapy.

Off-Label Prescribing in Pediatric Population
Off-label prescribing is widespread among pediatricians, and it is unlikely that this trend will soon be bound by a uniform legal framework. This is necessitated by the fact that there are four variables: the patient’s health condition, the physician’s experience and knowledge, the legislative measures (laws, directives, guidelines, and recommendations), and finally, the pharmaceutical industry. There is considerable concern worldwide about the use of off-label medicines in children.

Nanodelivery Systems and Constituents Derived from Novel Foods
Novel Food is a new category of food, regulated by the European Union Directive No. 2015/2283. This latter norm defines a food as “Novel” if it was not used “for human consumption to a significant degree within the Union before the date of entry into force of that regulation, namely 15 May 1997”. Due to their natural source, Novel Food can represent another new and not fully exploited reservoir of nutraceuticals. Indeed, Novel Food can also be considered an important source of raw matter to produce a nano-drug delivery system. The application of Novel Foods as new nanoceutical materials or bioactive compounds embedded into nanocarriers is a new research field, as these sources have been employed only in recent decades.

Polypharmacy in Older Patients with COVID-19
Polypharmacy is the use of multiple and potentially inappropriate medications (PIMs) that lack sufficient evidence of benefits and/or increase the risks of adverse drug reactions. It is an increasing problem among older adults. The global polypharmacy prevalence is 34.6% in patients with COVID-19, and polypharmacy in COVID-19 increases with age.

Discovering Amino Acid Transporter Inhibitors
Amino acid transporters are abundant amongst the solute carrier family and have an important role in facilitating the transfer of amino acids across cell membranes. Because of their impact on cell nutrient distribution, they also appear to have an important role in the growth and development of cancer. Naturally, this has made amino acid transporters a novel target of interest for the development of new anticancer drugs.

Quercetin Particularities
Quercetin is a flavonoid with a low molecular weight that belongs to the human diet’s phenolic phytochemicals and nonenergy constituents. Quercetin has a potent antioxidant capacity, being able to capture reactive oxygen species (ROS), reactive nitrogen species (RNS), and reactive chlorine species (ROC), which act as reducing agents by chelating transition-metal ions.
