Human papillomavirus (HPV) is an infection that can be sexually transmitted and result in health consequences. Persistent high-risk HPV infection can lead to various cancers and is the essential cause of cervical cancer. HPV vaccine can prevent the HPV infection and thus the incidence of cervical cancer. In this review we introduced the prevalence of HPV infection and vaccination, and the prevention and early detection of cervical cancer. We also introduced the present knowledge and awareness of HPV infection and HPV vaccine in Chinese...

OBJECTIVE: Control HIV replication requires continuous combined antiretroviral therapy (cART) as discontinuation of cART results in a rapid viral rebound. However, a few individuals exist who took cART for several years and did not show the expected viral rebound after treatment cessation. Most post-treatment controllers (PTCs) are early treated individuals. We report three cases who started cART during chronic infection. DESIGN: Patients were treated and monitored according to Italian guidelines...

OBJECTIVE: Birth diagnosis of HIV-1 infection offers an ideal opportunity for early antiretroviral treatment (ART) to limit HIV-1 reservoir size and limit disease progression. Although data on cellular HIV-1 DNA decay exist for children commencing treatment from 2-3 months of age, data is lacking for starting shortly after birth. DESIGN: We studied infants who initiated ART within 8 days after birth to assess HIV-1 DNA levels longitudinally. METHODS: Children were recruited from public health clinics in Cape Town where birth diagnosis of HIV-1 coupled with early ART initiation occurred...

The infection of legume plants by rhizobia is tightly regulated to ensure accurate bacterial penetration, infection and development of functionally efficient nitrogen-fixing root nodules. Rhizobial Nod Factors (NF) have key roles in the elicitation of nodulation signalling. Infection of white clover roots also involves the tightly regulated specific breakdown of the non-crystalline apex of cell walls in growing root hairs, which is mediated by Rhizobium leguminosarum bv. trifolii cellulase CelC2. Here, we have analyzed the impact of this endoglucanase on symbiotic signalling in the model legume Medicago truncatula...

The enzyme Zmp1 is a zinc-peptidase having a critical role in M. tuberculosis pathogenicity. Here we describe the identification of a small set of Zmp1 inhibitors based on a novel 8-hydroxyquinoline-2-hydroxamate scaffold. Among the synthesized compounds, 1c was the most potent Zmp1 inhibitor known to date, and its binding mode was analysed both through kinetic studies and molecular modelling, identifying critical interactions of 1c with the zinc-ion and residues in the active site. Effect of 1c on intracellular Mycobacterium survival was assayed in J774 murine macrophages infected with M...
