The skin is the organ that serves as the outermost layer of protection against injury, pathogens, and homeostasis with external factors; in turn, it can be damaged by factors such as burns, trauma, exposure to ultraviolet light (UV), infrared radiation (IR), activating signaling pathways such as Toll-like receptors (TLR) and Nuclear factor erythroid 2-related factor 2 (NRF2), among others, causing a need to subsequently repair and regenerate the skin. However, pathologies such as diabetes lengthen the inflammatory stage, complicating the healing process and, in some cases, completely inhibiting it, generating susceptibility to infections. Exosomes are nano-sized extracellular vesicles that can be isolated and purified from different sources such as blood, urine, breast milk, saliva, urine, umbilical cord bile cells, and mesenchymal stem cells. They have bioactive compounds that, thanks to their paracrine activity, have proven to be effective as anti-inflammatory agents, inducers of macrophage polarization and accelerators of skin repair and regeneration, reducing the possible complications relating to poor wound repair, and prolonged inflammation. This review provides information on the use of exosomes as a promising therapy against damage from UV light, infrared radiation, burns, and skin disorders.

Kidney diseases are expected to become the fifth leading cause of death by 2040. Several physiological failures classified as pre-, intra-, and post-renal factors induce kidney damage. Diabetes, liver pathologies, rhabdomyolysis, and intestinal microbiota have been identified as pre-renal factors, and lithiasis or blood clots in the ureters, prostate cancer, urethral obstructions, prostate elongation, and urinary tract infections are post-renal factors. Additionally, the nephrotoxicity of drugs has been highlighted as a crucial factor inducing kidney injuries. Due to the adverse effects of drugs, it is necessary to point to other alternatives to complement the treatment of these diseases, such as nephroprotective agents. Plants are a wide source of nephroprotective substances and can have beneficial effects in different levels of the physiological pathways which lead to kidney damage. In traditional medicines, plants are used as antioxidants, anti-inflammatories, diuretics, and anticancer agents, among other benefits. However, the mechanism of action of some plants empirically used remains unknown and scientific data are required to support their nephroprotective effects. The present work reviewed the plants with a beneficial effect on kidney diseases. The classification of nephroprotective plants according to the clinical definition of pre-renal, intrinsic, and post-renal factors is proposed to orient their use as complementary treatments.

Type 2 diabetes mellitus (T2DM) is the metabolic disease with the highest morbidity rates worldwide. The condition is characterized by hyperglycemia, insulin resistance, hyperlipidemia, and chronic inflammation, among other detrimental conditions. These decrease the efficiency of the immune system, leading to an increase in the susceptibility to bacterial infections. Maintaining an optimal blood glucose level is crucial in relation to the treatment of T2DM, because if the level of this carbohydrate is lowered, the risk of infections can be reduced. Currently, this is achieved using synthetic drug treatments that seek to moderately inhibit digestive enzymes (e.g., α-amylase and α-glucosidase), such as acarbose, voglibose, miglitol, etc. However, the use of these compounds also generates unwanted side effects such as nausea, diarrhea, stomach aches and a loss of appetite. Therefore, there is an increasing demand to find effective and safe alternatives for treating T2DM, such as herbal treatments. As a result, there has been a search for possible drugs from plants with both antidiabetic and antibacterial activity. This study presents a review of the molecular and cellular mechanisms of T2DM, secondary effects of the disease such as bacterial infections, and general comprehension of synthetic and natural product treatments to help patients.

Instant controlled pressure drop (DIC) is one of the emerging technologies in food processing; it can be used for drying, freezing and the extraction of bioactive molecules without damaging their properties. Legumes, such as lentils, are one of the most consumed foods in the world; however, they are mainly cooked by boiling, which causes the loss of antioxidant compounds. This work evaluated the effect of 13 different DIC treatments (with pressure ranges of 0.1–0.7 MPa and times of 30–240 s) on the content of polyphenols (Folin–Ciocalteu and High Performance Liquid Chromatography HPLC) and flavonoids (2-aminoethyl diphenylborinate) as well as the antioxidant activity (DPPH and TEAC) of green lentils. The DIC 11 treatment (0.1 MPa, 135 s) obtained the best release of polyphenols, which in turn are related to antioxidant capacity. The abiotic stress generated by DIC could lead to the breakdown of the cell wall structure, which favors the availability of antioxidant compounds. Finally, the most efficient conditions for DIC to promote the release of phenolic compounds and maintain antioxidant capacity were found under low pressures (<0.1 MPa) and short times (<160 s).

Eyelashes, in addition to fulfilling eye-protective functions, generate an aesthetic impact. Latanoprost is a prostaglandin analog, commonly used for the treatment of glaucoma and intraocular hypertension. The side effect reported most often is the stimulation of eyelash growth. The aim of this study was to evaluate the efficacy and safety of latanoprost in inducing eyelash growth and darkening. Thirty healthy volunteers were recruited in a 3-month, randomized, double-blind, placebo-controlled pilot study. A transparent eyelash mascara was used as a vehicle. The placebo group (n = 15) received only the vehicle, and the latanoprost group (n = 15) received the vehicle + 0.005% latanoprost. The participants were asked to apply the latanoprost topically to the eyelashes while avoiding entry into the eye, daily at night. The latanoprost group showed a significant increase in eyelash length and color change, while the placebo group maintained eyelash length and color throughout the study. The intraocular pressures of all the participants were maintained in normal ranges (10–20 mmHg). Topical application of both the placebo and the latanoprost medications was well tolerated; none of the participants withdrew, generated side effects, or developed any ophthalmic pathology. In conclusion, latanoprost is effective and safe to stimulate the growth of eyelashes.
