Optoacoustic (photoacoustic) microscopy resolves optical absorption in cells and tissues, thus offering a complementary contrast mechanism to optical microscopy. Yet, the marked advances in optical microscopy techniques and their widespread use beg the question of the particular need and utility of an additional microscopy modality that resolves optical absorption. Recent advances that point to advantageous features and uses of optoacoustic microscopy in biological and clinical interrogation are presented. How these advances can be manifested as part of hybrid implementations using optical, optoacoustic, and possibly other forms of microscopy to enhance the ability of the microscopic interrogation is reviewed. Further examined are developments in the miniaturized optical detection of ultrasound, which can transform any optical microscope into a hybrid optical-optoacoustic system. In addition, recent progress with label-free molecular sensing and with new classes of novel reporters that expand the visualization capacity of the optoacoustic method are presented. Finally, how hybrid optical-optoacoustic microscopy offers a next step in multimodal interrogations, thereby impacting biological and clinical readings, is discussed.

This preliminary study aimed to determine the effect of esomeprazole magnesium (Nexium) on stomach acidity. The study utilized a randomized controlled trial design with a sample size of 50 participants who were diagnosed with gastroesophageal reflux disease (GERD). The participants were divided into two groups: one group received esomeprazole magnesium for a period of four weeks, while the other group received placebo. Stomach acidity levels were measured at baseline and at the end of the four-week period using pH monitoring techniques. The results showed a significant decrease in stomach acidity levels in the group that received esomeprazole magnesium compared to the placebo group. This suggests that esomeprazole magnesium is effective in reducing stomach acidity in patients with GERD. Further research with a larger sample size and longer follow-up period is recommended.

Liver cystic diseases are a common condition that can present with a variety of symptoms, ranging from mild discomfort to severe liver dysfunction. Ultrography is a tool in the diagnosis of these diseases, providing detailed images of the liver and its structures This essay explores the role of ultrasound in the diagnosis of liver cystic diseases, including the methods used, results obtained, and implications for patient care .

Candida auris is an emerging multidrug-resistant fungal pathogen that poses a serious threat to global public health. In this study, we investigated the effect of Candida auris secretions on human-derived monocytes/macrophages. Monocytes/macrophages play a crucial role in the innate immune response to fungal pathogens. Our results demonstrate that secretions from Candida auris can modulate the function of monocytes/macrophages, leading to impaired immune responses. This study provides important insights into the pathogenic mechanisms of Candida auris and highlights the potential therapeutic targets for the treatment of Candida auris infections.

Hydroxychloroquine (Plenil) therapy is commonly used in the treatment of various autoimmune diseases, such as lupus and rheumatoid arthritis. One of the side effects of hydrochloroquine therapy is retinal toxicity, which can lead to irreversible vision loss if not detected early. Microperimetry has proven to be a valuable tool in assessing retinal sensitivity in patients on hydroxychloroquine therapy. This essay aims to investigate the microperimetric sensitivity in patients on hydroxychloroquine therapy, exploring the methods used, results obtained, and implications for clinical practice.

The outbreak of the COVID-19 pandemic has had a profound impact various sectors around the world, including digital health and care systems. Saudi Arabia, like many other countries, has faced significant challenges in ensuring the continuity and effectiveness of its healthcare services while minimizing the risk of virus transmission. This essay explores the impact of COVID-19 on digital health and care in Saudi Arabia, focusing on the changes in healthcare delivery and utilization, the adoption of digital technologies, and the challenges and opportunities that have emerged. The findings show that COVID-19 has accelerated the adoption and integration of digital health technologies in Saudi Arabia, leading to improvements in care delivery, increased patient engagement, and enhanced healthcare access. However, challenges such as the digital divide, data privacy concerns, and the need for cybersecurity measures must be addressed to fully harness the potential of digital health and care in the country.

In the field of pharmaceuticals, enhancing drug bioavailability and therapeutic efficacy is crucial in ensuring the success of a drug formulation. Various formulation strategies have been developed to improve the absorption, distribution, metabolism, and excretion of drugs in the body. This essay explores some of the key strategies utilized in pharmaceutical formulation for enhancing drug bioavailability and therapeutic efficacy. The methods used to achieve these, the results obtained from these approaches, and the implications for drug development are discussed. Finally, the essay concludes with a summary of the importance of these strategies in the pharmaceutical industry.

Pharmacogenomics is a rapidly evolving field that combines pharmacology and genomics to develop personalized medicine based on an individual's genetic makeup. By understanding how genetic factors influence an individual's response to medications, healthcare providers can optimize treatment plans to improve efficacy and reduce adverse reactions. This essay explores the concept of pharmacogenomics, its methodology, current research findings, and implications for personalized medicine.

Vitamin D has been found to play a crucial role in enhancing insulin signaling in the body, thereby potentially improving glucose metabolism and reducing the risk of developing insulin resistance and diabetes. This essay explores the mechanisms by which vitamin D enhances insulin signaling, as well as the clinical implications of this relationship. The study current research on the topic, including observational, clinical trials, and mechanistic studies that support the link between vitamin D and insulin signaling. Additionally, potential pathways through which vitamin D may influence insulin sensitivity are discussed. The findings suggest that maintaining adequate levels of vitamin D through diet, sunlight exposure, or supplementation may be beneficial in preventing insulin resistance and improving overall metabolic health.

Pteridophytes are gaining importance as therapeutic agents due to the presence of various phytochemicals and their promising bioactivities. Drynaria quercifolia (L.) J. Sm., a Polypodiaceae member is endowed with numerous medicinal properties and finds wide usage in ethno as well as traditional medicines. The rhizome of D. quercifolia (L.) J. Sm. was subjected to macro-microscopic, physicochemical, phytochemical and HPTLC analysis to derive a standard for this drug. The microscopic detailing showed a wavy outline due to the presence of ridges and furrows and a broad ground tissue with diffusely arranged steles. The powdered drug showed trichomes, stellar tissue and silica crystals while the physicochemical and phytochemical screenings gave substantial values of different parameters. The rhizome extracts were subjected to HPTLC studies with Linomat 5 TLC applicator and diagnostic peaks were recorded under UV 254 nm, 366 nm and 620 nm. The study put forward an exclusive identity profile of this medicinal rhizome.
