Fully integrated Kerr-lens mode-locked ceramic laser.

A 2.4 GHz Kerr-lens mode-locked laser, employing Yb:YO ceramic as the gain medium, has been fully integrated into a compact 61 mL volume. By optimizing the pump structure, all optical components of the laser are confined within a 34 × 78 mm area, enabling effective temperature control.

Value of CXCL13 in diagnosing asymptomatic neurosyphilis in HIV-infected patients.

Diagnosing asymptomatic neurosyphilis (ANS) in HIV-infected patients is difficult. A recent report suggested that CXCL13 is a promising diagnostic marker for neurosyphilis in HIV-positive patients. However, whether CXCL13 can be a diagnostic marker for ANS in HIV-infected patients remains unknown.

[Relationship between psychological distress and T lymphocyte in HIV/AIDS patients].

Objective: To explore the relationship between psychological distress and T lymphocyte counts in HIV/AIDS patients.

Methods: A total of 102 HIV/AIDS patients were measured by symptom check list (SCL-90), self-rating depressive scale (SDS) and self-rating anxiety scale (SAS). Patients were divided into 2 groups based on CD4+ T lymphocyte counts < 0.
