This review will be relevant to readers who are interested in using a PBPK model to develop new VDs.

Malassezia pachydermatis is a commensal organism of the skin, yet it may induce dermatitis and/or otitis. Lactoferricin (Lfcin) is an antimicrobial peptide obtained by the pepsin-mediated digestion of lactoferrin, a multifunctional innate-defence milk protein. The antibacterial activity of Lfcin is thought to cause alteration of bacterial membrane permeability, thus inducing cell death.

The aim of this study was to evaluate in vitro antifungal activity of different dilutions of Lfcin solution against M.pachydermatis strains isolated from ears of dogs and cats with otitis externa.

Fifty clinical Malassezia isolates from 40 dogs and 10 cats were tested. A dilution method in microtitre plates was used starting with a 20% Lfcin water solution. The different dilutions were 21 (13.3%), 11 (10%), 12 (6.7%), 15 (3.3%) and 110 (1.8%). Results were expressed as the value at which the growth of 50% (minimal fungicidal concentration MFC

) and 90% (MFC

) of yeast cells was inhibited.

All strains showed susceptibility to 20% Lfcin solution (100%). With 15 and 110 dilutions corresponding to 3.3% and 1.8% Lfcin solutions, all strains showed resistance. The MFC

and MFC

values were observed at 13.3% and 20% Lfcin solutions.

The results indicated that Lfcin solution exhibits the antimicrobial activity specific to antimicrobial peptides. In particular, the 20% solution can be effective in killing M.pachydermatis isolated strains. Some susceptibilities also are evident at lower concentrations of ≤6.7% for four strains.

Box5 cost We analyzed our data on tumors been treated between 2006 and 2016 at the Skin Cancer Center of an academic teaching hospital. Thousand hundred and ninety-four patients with 1296 SCC have been identified including 804 males (67.3%) and 390 females (32.7%). The mean age among females was significantly higher with (83.9 ± 7.9) years compared with males ([79.3 ± 8.1] years; P  less then  .001). The most common tumor localizations were outer ears (n = 227, 17.5%), scalp (216, 16.7%), and forehead (215, 16.6%). The majority of tumors was stage I. 31.9% of patients had previous SCC or Bowen's cancer, 29.1% had actinic keratoses. Major non-dermatological comorbidities were cardiovascular diseases and diabetes. SCC were treated by delayed Mohs surgery. First Mohs procedure resulted in R0 status in 83.9%. Most cases with R1 resection were located on nose and eyelids. For a subpopulation of patients (n = 105), a structured questionnaire study evaluated changes in sun protection behavior after skin cancer. After the confirmed diagnosis of a cutaneous SCC concerns about harm to the skin by intense sunlight was reported by 78.4% (76) of participants, with 92.0% among females versus 73.6% among males. Eighty percent of females and 76.8% of males wanted to care more about sun-protection in the future, spend less time 84.0% (females) and 72.5% (males) in the sun, and adapt their leisure activities for a better sun protection in 92.0% (females) and 81.9% (males). Secondary prevention in males needs improvement.It is important for the dermatopathologist to be adept in differentiating tissue artifacts from normal tissue variants and pathologies. Numerous tissue artifacts have been described to date; however, once we are familiar with the common artifacts that appear in our practice, we may not immediately recognize other confounders. For example, dermatopathologists in more temperate regions of the country may not be familiar with freezing artifact. In this case series, we present three common diagnoses in dermatopathology that were obscured by the extreme winter weather that severely impacted the Southern United States in February 2021 and discuss methods to prevent these artifacts.The World Health Organization (WHO) in Africa and Africa Center Disease Control (Africa CDC) urge the international community and different countries in Africa to ensure sustainable and concrete action to ensure equal and easy access to the COVID-19 vaccines, as different countries in Africa are still struggling to develop a safe and effective strategy to ensure equal vaccine distribution, if available. Africa CDC has called on the international community to come together to help Africa with COVID-19 vaccines to make equal the vaccine distribution among African countries as many cannot afford the vaccine costs due to the level of poverty and other negative factors. The African Union has endorsed the need for Africa to develop a framework to actively engage in easy accessibility to COVID-19 vaccines, which will allow different countries in Africa to take easy steps that will strengthen the local vaccine distribution system, building workforce skills and knowledge, and enrich outreach services in Africa. The article discusses the need for equal access in the distribution of COVID-19 vaccines in Africa, the challenges, and the necessary recommendations that can help to mitigate these challenges.High-yield resistant hybrids are used in cocoa fermentation and result in chocolates with different sensorial profiles. This work aimed to characterize the fermentation microbiologically and physicochemically. Hybrids CEPEC 2004, FA13, PH15, and CEPEC 2002 were used for fermentation. The yeast, acetic acid bacteria, lactic acid bacteria, and mesophilic bacteria population were evaluated in their respective medium. Carbohydrates and acids were detected using a high-performance liquid chromatography system, and volatiles were analyzed using gas chromatography-mass spectrometry equipment. Finally, a consumer acceptance test followed by a check-all-that-apply question and a temporal dominance of sensations assessment was performed in chocolate. The fermentation resulted in a typical succession yeast-dominated at first, followed by lactic acid, acetic acid, and mesophilic bacteria. In the pulp, carbohydrates and citric acid were consumed. Low concentrations of acetic acid (0.09-1.75 g/kg) were detected. Acids, esters, and alcohols were the most abundant groups.
