The past few years have seen the advent of several new antifungal agents. The echinocandin, caspofungin, has greatly expanded the antifungal armamentarium by providing a cell wall-active agent with candidacidal activity as well as demonstrated clinical efficacy in the therapy of aspergillosis refractory to available therapy. In addition, in clinical trials, caspofungin exhibited efficacy comparable to amphotericin B for invasive and/or fluconazole-resistant Candida infections. According to a randomised trial, voriconazole has added a significantly improved therapeutic option for primary therapy of invasive aspergillosis. Additionally, voriconazole may be used successfully as salvage therapy for other fungal infections, i.e. cryptococcosis. Despite the advances offered by each of these drugs, the morbidity and mortality associated with invasive fungal infections remains high. Considering the adverse effects of the available antifungal agents and the considerable costs for their application, meaningful clinical trials for a precise indication in different clinical situations are urgently needed.

Sulfur metabolism is an essential aspect of fungal physiology and pathogenicity. Fungal sulfur metabolism comprises anabolic and catabolic routes that are not well conserved in mammals, therefore is considered a promising source of prospective novel antifungal targets. To gain insight into sulfur-related metabolism during infection, we used a NanoString custom nCounter-TagSet and compared the expression of 68 key metabolic genes in different murine models of invasive pulmonary aspergillosis, at 3 time-points, and under a variety of conditions.

Background: Heavy metal contamination, particularly from lead (Pb), poses a significant threat to plant agriculture worldwide, adversely affecting growth, physiological functions, and yield. Signalling molecules such as calcium and salicylic acid are known to mitigate various stresses in plants, prompting this study to explore their interaction with Pb stress in wheat.
Methods: A pot experiment was conducted in which wheat grains were primed with either distilled water, 5 mM calcium (Ca), or 0.
Comparing the effects of Mycozin and Clotrimazole 1% creams on vaginal candidiasis: a triple-blinded randomized controlled trial.

Clotrimazole 1% and Mycozin vaginal cream have been reported to be effective in relieving the symptoms of vulvovaginitis caused by Candida. The resistance to azole compounds, and the side effects of chemical drugs have been reported following azole therapy. It was hypothesized that Mycozin is at least as effective as Clotrimazole in treating vaginal candidiasis.

Background: Systemic lupus erythematosus (SLE) is a complex and incurable autoimmune disease, so several drug remission for SLE symptoms have been developed and used at present. However, treatment varies by patient and disease activity, and existing medications for SLE were far from satisfactory. Novel drug targets to be found for SLE therapy are still needed.

Plant sphingolipids are lipophilic membrane components essential for different cellular functions but they also act as signaling molecules in various aspects of plant development. However, the interaction between plant sphingolipids and abscission remains largely uncharacterized. Here, the possible role of sphingolipids in regulating fruit abscission was examined in the abscission zone (AZ) of olive fruit.
