Background & Objective: Prostatic adenocarcinoma (PAC) is the second most prevalent cancer and the fifth leading cause of cancer death in men worldwide. Additionally, pathologists may face problems diagnosing it reliably and may need more than one marker. Thus, the search for new immunohistochemical biomarkers becomes mandatory.

Pancreatic ductal adenocarcinoma (PDAC) and ampullary carcinoma (AAC) are lethal malignancies with modest benefits from surgery. SOX2 and STIM1 have been linked to anticancer activity in several human malignancies. This study included 94 tumor cases: 48 primary PDAC, 25 metastatic PDAC, and 21 primary AAC with corresponding non-tumor tissue.

Ferulic acid (FA) has powerful antioxidant and antitumor activities, but it has low bioavailability owing to its poor water solubility. Our aim is to formulate polymeric mixed micelles loaded with FA to overcome its poor solubility and investigate its potential anticancer activity via miRNA-221/TP53INP1 axis-mediated autophagy in colon cancer. A D-optimal design with three factors was used for the optimization of polymeric mixed micelles by studying the effects of each of total Pluronics mixture (mg), Pluronic P123 percentage (%w/w), and drug amount (mg) on both entrapment efficiency (EE%) and particle size.

The aim of the current study is to explore the potential of artificial intelligence (AI) when integrated with Quality by Design (QbD) approach in the formulation of a poorly water-soluble drug, for its potential use in carcinoma. Silymarin is used as a model drug for its potential effectiveness in liver cancer. A detailed QbD approach was applied.

Background: Despite recent advances in therapy modalities of colorectal cancer (CRC), it is still the third cause of cancer-related deaths worldwide. Thus, the search for new target therapies became mandatory. DDR1 is a collagen receptor that has a suggested role in cellular proliferation, tumor invasion, and metastasis.

Background: Androgenetic alopecia (AGA) is a common cause of hair loss in both genders that may be associated with disturbed systemic metabolism. Irisin is a hormone-like myokine that greatly influences systemic metabolism and is linked to cardiovascular diseases.

Aim: To detect irisin role in AGA and its associated metabolic syndrome (MetS) and cardiovascular risk.

Vanillic acid (VA) is a phenolic compound with potential antioxidant activity, which improves ischemia-induced myocardial degeneration, by reducing oxidative stress; however, it suffers poor bioavailability owing to its poor solubility. VA-loaded pharmacosomes were optimized using a central composite design, where the effect of phosphatidylcholine:VA molar ratio and the precursor concentration were studied. An optimized formulation (O) was prepared and tested for the release rate of VA, in vivo bioavailability, and cardioprotective potential on myocardial infarction-induced rats.

The mechanism of transition of ductal carcinoma in situ (DCIS) to invasive cancer is elusive but recently changes in the myoepithelial cells (MECs) have been implicated. The aim of this study is to investigate the changes in gene profile of MECs in DCIS that could compromise their tumor suppressor function leading to promotion of tumor progression. Immuno-laser capture microdissection (LCM) was used to isolate MECs from normal and DCIS breast tissues followed by whole genome expression profiling using Affymetrix HGU-133 plus2.

Aim: To evaluate the effectiveness of topical insulin-liposomal gel in aphthous ulcer treatment.

Methods: 80 participants with minor aphthous ulcers were randomly divided to receive either topical insulin-liposomal gel or placebo gel (once daily) for 6 days. Assessment of outcomes included visual analog scale (VAS) for pain (primary outcome), and secondary outcomes included ulcer duration and impact of treatment on quality of life using the Oral Health Impact Profile 14 (OHIP-14).

Breast cancer (BC) remains the most prevalent female cancer in Egypt and worldwide. Microfibrillar-associated protein 5 (MFAP5) is a multifunctional glycoprotein. Although MFAP5 gene was among the genes that found globally expressed in human cancers, it had been only recently reported in few cancer research studies.

Timolol Maleate (TiM), a nonselective β-adrenergic blocker, is a potent highly effective agent for management of hypertension. The drug suffers from poor oral bioavailability (50%) due to its first pass effect and a short elimination half-life of 4 h; resulting in its frequent administration. Transdermal formulation may circumvent these problems in the form of protransfersomes.

Timolol maleate (TiM), a nonselective β-adrenergic blocker, is a potent highly effective agent for management of hypertension. The drug suffers from extensive first pass effect, resulting in a reduction of oral bioavailability (F%) to 50% and a short elimination half-life of 4 h; parameters necessitating its frequent administration. The current study was therefore, designed to formulate and optimize the transfersomal TiM gel for transdermal delivery.
