Cyclodextrin Multicomponent Complexes: Pharmaceutical Applications
Cyclodextrins (CD) are a family of macromolecules obtained by enzymatic degradation of starch. Their structure resembles a truncated cone, with a somewhat lipophilic central cavity and an external hydrophilic surface. Due to these characteristics the pharmaceutical applications are mostly related to the ability of CDs to form inclusion complexes, formed by interactions between guest (drug) and host (CD) molecules, and they have the ability to modulate several properties positively affecting the performances and therapeutic profiles of drugs. Besides, a drug–CD complex with the addition of an auxiliary substance, that are called multicomponent or ternary complex, can have a synergic effect, allowing the use of low concentrations of the host compounds, thereby optimizing the cost, toxicity and formulation volume in the final product. Also, these additives such as amino acids, organic acids and bases, and water-soluble polymers interacting with CDs can modulate in vitro and in vivo drug dissolution, thereby modifying the drug’s pharmacokinetic profile.

Aromatic Plants Metabolic Engineering
Secondary metabolites of aromatic plants are used in many health applications as drugs, pheromones, insecticides, fragrances, and antioxidants. Due to the huge commercial demand for these secondary metabolites, the need to overcome the insufficient productivity of aromatic plants has become a significant challenge. Plant breeding is a traditional, labor-intensive, and limited method to improve the ability of aromatic plants to produce secondary metabolites.

Thermosensitive Liposomal Doxorubicin
Thermo-sensitive liposomes (TSLs) offer the most promising approach for more efficient doxorubicin (DOX) delivery to the tumor at mild hyperthermic temperatures (39-42 ̊C)

Copper Chelators and cDDP Resistance
The platinum (Pt)-containing antitumor drugs including cisplatin (cis-diamminedichloroplatinum II, cDDP), carboplatin, and oxaliplatin, have been the mainstay of cancer chemotherapy. These drugs are effective in treating many human malignancies. The major cell-killing target of Pt drugs is DNA. Recent findings underscored the important roles of Pt drug transport system in cancer therapy. It was demonstrated that by reducing cellular Cu bioavailable levels by Cu chelators, hCtr1 is transcriptionally upregulated by transcription factor Sp1, which binds the promoters of Sp1 and hCtr1. In contrast, elevated Cu poisons Sp1, resulting in suppression of hCtr1 and Sp1, constituting the Cu-Sp1-hCtr1 mutually regulatory loop.

Drug Delivery Approaches for OAB
Overactive bladder syndrome (OAB) is characterised by urgency symptoms, with or without urgency incontinence, usually with frequency and nocturia and severely affects the quality of life.

Thiolated-Polymer-Based Nanoparticles
Thiomers (or thiolated polymers) have broken through as avant-garde approaches in anticancer therapy. Their distinguished reactivity and properties, closely linked to their final applications, justify the extensive research conducted on their preparation and use as smart drug-delivery systems (DDSs).

Clinical Considerations of Benzodiazepines
Benzodiazepines (BZDs) are among one of the most widely prescribed drug classes in the United States. BZDs are a class of psychoactive drugs known for their depressant effect on the central nervous system (CNS). They quickly diffuse through the blood–brain barrier to affect the inhibitory neurotransmitter GABA and exert sedative effects. One of the debilitating side effects of BZDs is their addictive potential. The dependence on BZDs generally leads to withdrawal symptoms, requiring careful tapering of the medication when prescribed. Regular use of BZDs has been shown to cause severe, harmful psychological and physical dependence, leading to withdrawal symptoms similar to that of alcohol withdrawal.

Marine Products in Colorectal and Pancreatic Cancers Treatment
Gastrointestinal cancer refers to malignancy of the accessory organs of digestion, and it includes colorectal cancer (CRC) and pancreatic cancer (PC). Worldwide, CRC is the second most common cancer among women and the third most common among men. PC has a poor prognosis and high mortality, with 5-year relative survival of approximately 11.5%. Conventional chemotherapy treatments for these cancers are limited due to severe side effects and the development of drug resistance. Therefore, there is an urgent need to develop new and safe drugs for effective treatment of PC and CRC. Historically, natural sources—plants in particular—have played a dominant role in traditional medicine used to treat a wide spectrum of diseases. In recent decades, marine natural products (MNPs) have shown great potential as drugs, but drug leads for treating various types of cancer, including CRC and PC, are scarce. To date, marine-based drugs have been used against leukemia, metastatic breast cancer, soft tissue sarcoma, and ovarian cancer.

Adverse Side Effects of Long-Term Lithium Therapy
Lithium remains the drug of first choice for prophylactic treatment of bipolar disorder, preventing the recurrences of manic and depressive episodes. The longitudinal experiences with lithium administration greatly exceed those with other mood stabilizers. Among the adverse side effects of lithium, renal, gastrointestinal, neurological, thyroid, metabolic, cognitive, dermatological, cardiologic, and sexual are listed. Probably, the most important negative effect of lithium, occurring mostly after 10–20 years of its administration, is interstitial nephropathy.

Practical Considerations for Next-Generation Adjuvant Development and Translation
Throughout the last two decades, there has been increasing focus on the discovery and translation of new immune-stimulating agents. These compounds are often collectively referred to as adjuvants due to their precedent of use in vaccine development. There has been an expansion in the application of adjuvants in oncology and other areas as the understanding and definition of adjuvants continue to grow. Adjuvants stimulate key cell types in the innate immune system and can influence the scale and class of immune response directed towards a given antigen or antigens.
