An effective procedure used metal-organic framework for determination of cadmium ions in real tap water and human blood plasma samples.

A newly developed 2H5MA-MOF sensor by covalently linking NH-MIL-53(Al) with 2'-Hydroxy-5'-methylacetophenon, designed for highly sensitive and selective detection of Cd ions using fluorometric methods. Detailed structural and morphological analyses confirmed the sensor's unique properties. It demonstrated an impressive linear detection range from 0 to 2 ppm, with an exceptionally low detection limit of 5.

Quantification of arsenic in real samples using a spectrophotometric cloud point extraction of the formed ion pair with astrazon orange G.

A novel cloud-point extraction (CPE) procedure for the determination of ultra-trace amounts of arsenic species in real samples, purchased from the local market by spectrophotometer was developed. Inorganic arsenic species analysis in water, beverages, and foods has become increasingly important in recent years, as arsenic species are considered carcinogenic and are assessed at significant levels in samples. The technique is established on a selective ternary complex of As(V) with astrazon orange G (AOG) in the presence of tartaric acid and polyethylene glycol tertoctylphenyl ether (Triton X-114) at pH 4.

Revolutionizing scandium detection in real samples: Unleashing the power of sol-gel-based optical sensor.

The development of a highly selective and ultra-sensitive optical sensor for detecting scandium (Sc) ions involves incorporating the reagent 2,3-dichloro-6-(3-carboxy-2-hydroxy-1-naphthylazo)quinoxaline (DCHNAQ) into a silica sol-gel thin film on a glass substrate. This innovative approach utilizes tetraethoxy-silane (TEOS) as the precursor, maintaining a sol-gel pH level of 4.5, a water-to-alkoxide ratio of 5:1, and a DCHNAQ concentration of 5.

A comparison of kinesio taping and classical massage in addition to cervical stabilization exercise in patients with chronic neck pain.

Background And Purpose: Studies comparing the effectiveness of kinesio taping (KT) and classical massage (CM) in chronic neck pain (CNP) are scarce. This study aimed to compare the effects of KT and CM in addition to cervical stabilization exercise (CSE) in patients with CNP.

Materials And Methods: Patients were randomly allocated to KT + CSE and CM + CSE groups.

Conservative laparoscopic approach to adnexal torsion.

Objective: To evaluate the conservative laparoscopic approach to adnexal torsion during reproductive age.

Methods: We present 18 patients with adnexal torsion between January 1997 and December 2005. Patients treated conservatively were controlled by ultrasonography during the postoperative period.
