ALDH in Gynecologic Malignancies
Gynecologic cancers cause over 600,000 deaths annually in women worldwide. The development of chemoresistance after initial rounds of chemotherapy contributes to tumor relapse and death due to gynecologic malignancies. In this regard, cancer stem cells (CSCs), a subpopulation of stem cells with the ability to undergo self-renewal and clonal evolution, play a key role in tumor progression and drug resistance. Aldehyde dehydrogenases (ALDH) are a group of enzymes shown to be robust CSC markers in gynecologic and other malignancies. These enzymes also play functional roles in CSCs, including detoxification of aldehydes, scavenging of reactive oxygen species (ROS), and retinoic acid (RA) signaling, making ALDH an attractive therapeutic target in various clinical scenarios. In this review, we discuss the critical roles of the ALDH in driving stemness in different gynecologic malignancies. We review inhibitors of ALDH, both general and isoform-specific, which have been used to target CSCs in gynecologic cancers. Many of these inhibitors have been shown to be effective in preclinical models of gynecologic malignancies, supporting further development in the clinic. Furthermore, ALDH inhibitors, including 673A and CM037, synergize with chemotherapy to reduce tumor growth. Thus, ALDH-targeted therapies hold promise for improving patient outcomes in gynecologic malignancies.

Aldose Reductase (AR, ALR2)
Aldose reductase (AR, ALR2), the first enzyme of the polyol pathway, is implicated in the pathophysiology of diabetic complications. Aldose reductase inhibitors (ARIs) thus present a promising therapeutic approach to treat a wide array of diabetic complications.

Algae and Fungi: use in Pre-Hispanic Mexico
The use of microorganisms in Mexico began before the Spanish conquest. Grains and fruit were fermented for thousands of years around the world, and Mexico was no exception. Many beverages are still prepared nowadays using an assortment of different microorganisms. These beverages use several yeasts, including Saccharomyces and non-Saccharomyces species. Although not conclusive, it has been suggested (and strong evidence points towards it) that pre-Hispanic cultures not only fermented beverages, but also distilled them.

Algae Food Products as a Healthcare Solution
Diseases such as obesity; cardiovascular diseases such as high blood pressure, myocardial infarction and stroke; digestive diseases such as celiac disease; certain types of cancer and osteoporosis are related to food. On the other hand, as the world’s population increases, the ability of the current food production system to produce food consistently is at risk. As a result, intensive agriculture has contributed to climate change and a major environmental impact. Research is, therefore, needed to find new sustainable food sources. One of the most promising sources of sustainable food raw materials is macroalgae. Algae are crucial to solving this nutritional deficiency because they are abundant in bioactive substances that have been shown to combat diseases such as hyperglycemia, diabetes, obesity, metabolic disorders, neurodegenerative diseases and cardiovascular diseases.

Algae Metabolites in Cosmeceutical
Cosmeceuticals are topical cosmetic-pharmaceutical hybrids which refer to a cosmetic product with active ingredients claiming to have medicinal or drug-like benefits to skin health. Marine algae are rich in bioactive substances that have shown to exhibit strong benefits to the skin, particularly in overcoming rashes, pigmentation, aging, and cancer.

Algae-Derived Compounds against PM-induced Diseases
Air pollution has recently become a subject of increasing concern in many parts of the world. The World Health Organization (WHO) estimated that nearly 4.2 million early deaths are due to exposure to fine particles in polluted air, which causes multiple respiratory diseases. As a natural product, algae can be an alternative treatment due to potential biofunctional properties and advantages.

Algorithm for Dysphagia Screening
Dysphagia is often unrecognized because many people are unfamiliar with symptoms and signs of dysphagia besides choking during swallowing. Dysphagia screening is therefore important. A good screening should be a quick process and minimally invasive but can determine the likelihood of dysphagia. Here, an algorithm for dysphagia screening is introduced. The algorithm can be used for people unspecialized in dysphagia.

ALK Inhibitors in NSCLCs
The discovery of the EML4-ALK fusion gene in a limited subset of patients affected by NSCLC and the subsequent clinical development of crizotinib in 2011 has been an impressive milestone in lung cancer research. Unfortunately, acquired resistances regularly develop, hence disease progression occurs. Afterward, modern tyrosine kinase inhibitors (TKIs), such as ceritinib, alectinib, brigatinib, and lorlatinib, have been approved by the Food and Drug Administration (FDA) for the management of anaplastic lymphoma kinase (ALK)-positive NSCLCs. Several compounds are currently under investigation to achieve the optimal strategy of therapy.
