Hypothermia: Pathophysiology and the propensity for infection.

Hypothermia in combination with infection presents a complex challenge in clinical and battlefield medicine. Multifaceted physiological and immunological consequences of hypothermia drastically change the risk, progression, and treatment of a concomitant infection. Managing hypothermia and infection in extreme cold settings is particularly relevant in an era with increased risk of military operations in Polar climates.

Invasive Fungal Diseases of Combat Wounds: Burden, Epidemiology, and Mycology.

During the last two decades, wound invasive fungal diseases (WIFDs) have reemerged as important causes of mortality and morbidity in military personnel and civilian casualties in war areas. Historically, mycotic infections acquired in combat operations during Vietnam War and were associated with burn wounds. Modern combat related WIFDs are almost exclusively associated with severe traumatic events which encompass blast exposure as the primary mechanism of injury and subsequent extremity amputation and extensive blood loss.

Search for Rare b→dℓ^{+}ℓ^{-} Transitions at Belle.

We present the results of a search for the b→dℓ^{+}ℓ^{-} flavor-changing neutral-current rare decays B^{+,0}→(η,ω,π^{+,0},ρ^{+,0})e^{+}e^{-} and B^{+,0}→(η,ω,π^{0},ρ^{+})μ^{+}μ^{-} using a 711  fb^{-1} data sample that contains 772×10^{6}  BB[over ¯] events. The data were collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. We find no evidence for signal and set upper limits on branching fractions at the 90% confidence level in the range (3.

Measurements of the Branching Fraction, Polarization, and CP Asymmetry for the Decay B^{0}→ωω.

We present a comprehensive study of B^{0}→ωω decays using 772×10^{6}  BB[over ¯] pairs collected with the Belle detector at the KEKB e^{+}e^{-} collider. This process is a suppressed charmless decay into two vector mesons and can exhibit interesting polarization and CP violation. The decay is observed for the first time with a significance of 7.

Search for Baryon-Number-Violating Processes in B^{-} Decays to the Ξ[over ¯]_{c}^{0}Λ[over ¯]_{c}^{-} Final State.

We report the results of the first search for B^{-} decays to the Ξ[over ¯]_{c}^{0}Λ[over ¯]_{c}^{-} final state using 711  fb^{-1} of data collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. The results are interpreted in terms of both direct baryon-number-violating B^{-} decay and Ξ_{c}^{0}-Ξ[over ¯]_{c}^{0} oscillations which follow the standard model decay B^{-}→Ξ_{c}^{0}Λ[over ¯]_{c}^{-}. We observe no evidence for baryon number violation and set the 95% confidence-level upper limits on the ratio of baryon-number-violating and standard model branching fractions B(B^{-}→Ξ[over ¯]_{c}^{0}Λ[over ¯]_{c}^{-})/B(B^{-}→Ξ_{c}^{0}Λ[over ¯]_{c}^{-}) to be <2.
