Plasmodium falciparum causes one of the deadliest forms of malaria and resistance to the currently available drugs makes it imperative to develop new, safe and potent drugs. Parasites such as P. falciparum are unable to synthesise purines de novo and to this end often have multiple purine uptake and salvage systems. With this in mind, we have designed and synthesised libraries of purine analogues as potential anti-malarial agents. Herein, we report three compounds with promising activity against the highly chloroquine-resistant VS1 P. falciparum namely: N(6)-hydroxyadenine (1c), 2-amino-N(6)-aminoadenosine (2b) and 2-amino-N(6)-amino-N(6)-methyladenosine (4b).

Background: N6-methyladenosine (m6A) is one of the most conserved internal RNA modifications, which has been implicated in many biological processes, such as apoptosis and proliferation. Wilms tumor 1-associating protein (WTAP), as a key component of m6A methylation, is a nuclear protein that has been associated with the regulation of proliferation and apoptosis. Rheumatoid arthritis (RA), a systemic, infiltrating autoimmune disease, is characterized by synovial hyperplasia.

Cisplatin is a common and highly effective chemotherapeutic agent whose nephrotoxic side effect is well-characterized. Sodium thiosulfate (STS), an FDA-approved hydrogen sulfide (HS) donor drug, is emerging as a chemoprotective agent against cisplatin-induced nephrotoxicity (CIN). In this study, we investigated the chemoprotective mechanism of STS in a rat model of CIN.

The lily is a globally popular cut flower, and managing dormancy in lily bulblets is essential for continuous, year-round production. While nitric oxide (NO) has been shown to influence seed dormancy and germination, its role in dormancy release in lilies was previously unconfirmed. In this study, we investigated the effects of NO on dormancy release in lily bulblets using SNP and c-PTIO.

Rotation of the bacterial flagellum, the first identified biological rotary machine, is driven by its stator units. Knowledge gained about the function of stator units has increasingly led to studies of rotary complexes in different cellular pathways. Here, we report that a tetrameric PilZ family protein, FlgX, is a structural component underneath the stator units in the flagellar motor of .

Rationale: Mass vaccination, low cost of immunoglobulins, and new drugs led to the emergence of new, unusual patterns of hepatitis B serum markers. This study reported a rare case of hepatitis B with all 5 positive serum markers, including HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb.
Patient Concerns: A 30-year-old female patient was admitted due to abnormal liver function.
