A heteroscedastic regression based on the odd log-logistic Marshall-Olkin normal (OLLMON) distribution is defined by extending previous models. Some structural properties of this distribution are presented. The estimation of the parameters is addressed by maximum likelihood.

- The study focuses on K. pneumoniae producing carbapenemase (KPC-Kpn) and its significance in hospital infections, as it carries the blaKPC genes which make it a primary concern.
- Researchers analyzed 54 carbapenem-resistant K. pneumoniae isolates from hospitalized patients, using methods like PCR and broth microdilution to confirm resistance and analyze genetic content.
- Findings showed all isolates were KPC-2 subtype and resistant to common antibiotics, with an observed increase in infections due to the loss of porin expression, highlighting the urgent need for improved infection control measures in hospitals.
Antimicrobial activity evaluation and comparison of methods of susceptibility for Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacter spp. isolates.

The production of KPC (Klebsiella pneumoniae carbapenemase) is the major mechanism of resistance to carbapenem agents in enterobacterias. In this context, forty KPC-producing Enterobacter spp. clinical isolates were studied.

In this study, our aim was twofold. First, we sought to evaluate the effects of cognitive behavioral group therapy (CBGT) on neurocognitive functions in OCD patients.

The challenge is to find new compounds that can control KPC producing-Kpn infections.
