Complement-mediated lysis of tumor cell lines is not enhanced by NA-Fc4 expression.

open access: yes, 2023
Naïve A549-NLR (panel A) and SKOV3-NLR (panel B) cells as well the corresponding cell lines that stably express NA-Fc4 were left untreated or incubated with 20% normal human serum (NHS) or heat-inactivated NHS (HI).

Hypocomplementemia is associated with worse renal survival in ANCA-positive granulomatosis with polyangiitis and microscopic polyangiitis. [PDF]

open access: yesPLoS ONE, 2018
Recent data suggest the existence of a complement alternative pathway activation in the pathogenesis of antineutrophilic cytoplasmic antibody (ANCA)-associated vasculitis (AAV), a condition that remains poorly understood.

p-divisibility of conjugacy class sizes and normal p-complements [PDF]

open access: yesJournal of Group Theory, 2014
Abstract Let N be a normal subgroup of a group G and let p be a prime. We prove that if the p-part of |x| G is a constant for every prime-power order element x ∈ N∖Z(N), then N is solvable and has normal p-complement.

A novel approach to inhibit HIV-1 infection and enhance lysis of HIV by a targeted activator of complement

open access: yesVirology Journal, 2009
Background The complement system is one of the most potent weapons of innate immunity. It is not only a mechanism for direct protection against invading pathogens but it also interacts with the adaptive immunity to optimize the pathogen-specific humoral ...

Complement C3 serum levels in anorexia nervosa: a potential biomarker for the severity of disease?

open access: yesAnnals of General Psychiatry, 2011
Background Anorexia nervosa carries the highest mortality rate of any psychiatric disorder. Even the most critically ill anorexic patients may present with normal 'standard' laboratory values, underscoring the need for a new sensitive biomarker.

On existence of normal p-complement of finite groups with restrictions on the conjugacy class sizes

open access: yesCommunications in Mathematics, 2022
The greatest power of a prime $p$ dividing the natural number $n$ will be denoted by $n_p$. Let $Ind_G(g)=|G:C_G(g)|$. Suppose that $G$ is a finite group and $p$ is a prime. We prove that if there exists an integer $\alpha>0$ such that $Ind_G(a)_p\in \{1,p^{\alpha}\}$ for every $a$ of $G$ and a $p$-element $x\in G$ such that $Ind_G(x)_p>1$, then $
