Characterizing the Patterns of Cervical Cancer Symptom Recognition, Symptom Response, and Associated Factors Among Patients Treated in a Teaching Hospital in Ghana.

Background: Cervical cancer is a major global health issue and ranks as the second leading cause of cancer-related deaths among women in Ghana.

Objective: This study aimed to explore and characterize the patterns of symptom recognition associated with cervical cancer and the symptom responses among women in Ghana.

Methods: A descriptive qualitative design utilizing 20 individual semistructured interview sessions was used.

Theoretical studies on the reaction mechanisms of the oxidation of tetramethylethylene using MOCl (M=Mn, Tc and Re).

A theoretical study on the reaction mechanisms of the addition of transition metal oxo complexes of the type MOCl (M = Mn, Tc, and Re) to tetramethylethylene (TME) is presented. Theoretical calculations using B3LYP/LACVP* and M06/LACVP* (LACVP* is a combination of the 6-31G(d) basis set along with LANL2DZ pseudopotentials on the metallic centres) were performed and the results are discussed within the framework of reaction energetics. The nature of the stability of the reaction mechanisms was equivalent for both theories.

A DFT study on the reaction mechanisms of the oxidation of ethylene mediated by technetium and manganese oxo complexes.

The oxidation of ethylene catalyzed by manganese and technetium oxo complexes of the type MOL (M = Tc, Mn, and L = O, Cl, F, OH, Br, I) on both singlet and triplet potential energy surfaces (PESs) have been studied. All molecular structures were stable on the singlet PES except for the formation of the dioxylate intermediate for the MnOL (L = O, Cl, F, OH, Br, I) catalyzed pathway. Frontier molecular orbital calculations showed that electrons flow from the HOMO of ethylene into the LUMO of the metal-oxo complex for all complexes studied except for MOL (M = Tc, Mn, and L = O) where the vice versa occurs.

Impact of chronic stylet-feeder infestation on folivore-induced signaling and defenses in a conifer.

Our understanding of how conifers respond biochemically to multiple simultaneous herbivore attacks is lacking. Eastern hemlock (Tsuga canadensis; 'hemlock') is fed on by hemlock woolly adelgid (Adelges tsugae; 'adelgid') and by later-instar gypsy moth (Lymantria dispar; 'gypsy moth') caterpillars. The adelgid is a stylet-feeding insect that causes a salicylic acid (SA)-linked response in hemlock, and gypsy moth larvae are folivores that presumably cause a jasmonic acid (JA)-linked response.
