Expanded HPV Genotyping by Single-Tube Nested-Multiplex PCR May Explain HPV-Related Disease Recurrence.

The role of the human papillomavirus (HPV) in the establishment of cervical cancer has driven studies to find more effective methods of viral detection so that early intervention strategies can be performed. However, the methods still have limitations, especially regarding detecting the different genotypes simultaneously. We have developed a high-throughput system using a single-tube nested-multiplex polymerase chain reaction (NMPCR) for the detection of 40 HPV genotypes using capillary electrophoresis.

subsp. Strains Fb7 and 9a5c from Citrus Display Differential Behavior, Secretome, and Plant Virulence.

colonizes the xylem of various cultivated and native plants worldwide. Citrus production in Brazil has been seriously affected, and major commercial varieties remain susceptible to Citrus Variegated Chlorosis (CVC). Collective cellular behaviors such as biofilm formation influence virulence and insect transmission of .

Upregulation of tropomyosin alpha-4 chain in patients' saliva with oral squamous cell carcinoma as demonstrated by Phage display.

Patients with oral squamous cell carcinoma (OSCC) present significant alterations in their saliva proteome. We have used the shotgun Phage Display (PD) technology to identify candidate proteins that were upregulated in saliva of OSCC by selecting ligands to salivary proteins from a single-chain variable fragment (scFv) PD combinatorial library. After two selection cycles, the highly reactive clone scFv-D09 was able to distinguish saliva of OSCC patients from healthy subjects by enzyme-linked immunosorbent assay (ELISA) with sensitivity and specificity of 96.

Medium/Long wavelength sensitive opsin diversity in Pitheciidae.

New World primates feature a complex colour vision system. Most species have polymorphic colour vision where males have a dichromatic colour perception and females can be either dichromatic or trichromatic. The adaptive value of high allelic diversity of opsins, a light sensitive protein, found in primates' eyes remains unknown.
