Carbon monoxide adsorption on NaY zeolite and impregnated with 5% niobium: Characteristics and fixed‐bed study

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Schematic of the CO adsorption process in a fixed‐bed column containing pure NaY zeolite and Nb‐modified NaY (NaY–5%Nb). On the left, breakthrough curves and temperature profiles highlight the dynamic performance and thermal effects during CO adsorption.

Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Investigating the Reactivity and Selectivity in Nucleophilic Fluorination of Secondary Alkyl Bromides and Mesylates: Assessment of the Effect of Counterion and Bulky Alcohols

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Hydrogen bonding provided by pinacol or 2‐trifluoromethyl‐2‐propanol enhances the selectivity of nucleophilic fluorination of several secondary alkyl bromides or mesylates. Synthesis of secondary alkyl fluorides via nucleophilic substitution faces the problem of high competition with E2 processes. This competition depends on the chemical environment of

Validation and Application of an HPLC–UV Method for the Quantification of 3‐O‐Methylquercetin in Nasal Mucosa

open access: yesELECTROPHORESIS, EarlyView.
This study improved an HPLC–UV method for quantifying 3‐O‐methylquercetin in porcine nasal mucosa following ICH M10 and ANVISA (Brazil) guidelines, assessing selectivity, linearity, accuracy, precision, and robustness. The method was applied for the first time to evaluate release, permeation, and retention profiles of a nasal formulation.

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Insulin‐like growth factor 1 receptor correlates with verbal memory in ILAE type 2 hippocampal sclerosis

open access: yesEpilepsia, EarlyView.
Abstract Objective Long‐term memory deficits are often seen in patients with temporal lobe epilepsy (TLE). Recently, studies showed that patients with hippocampal sclerosis (HS) type 2, which presents with severe neuron loss in CA1 only, performed within the normal range. However, up to 30% of HS type 2 cases have memory deficits.

Abnormal functional connectivity patterns in temporal lobe epilepsy—An international ENIGMA‐epilepsy study

open access: yesEpilepsia Open, EarlyView.
Abstract Objectives Temporal lobe epilepsy (TLE) impacts multiple brain networks. Aberrant functional connectivity has been demonstrated in resting‐state networks (RSNs) that mediate higher brain functions in TLE. This study aimed to identify the reproducible patterns of altered functional connectivity in TLE in a large, international cohort through ...
