Analysis of 239 ordinary and severe cases of COVID-19: Clinical features and treatment.

This study retrospectively analyzed the clinical characteristics of patients with new coronavirus infection (COVID-19) and summarizes the treatment experience. A total of 239 COVID-19 patients admitted to the Hajar Hospital, Aja University of Medical Science, Tehran, Iran from March 22, 2020 to May 18, 2020 were selected, including 176 cases in the ordinary group and 63 cases in the severe/critical group. We collected and compared the clinical data of the two groups of patients, including general conditions, clinical symptoms, signs, laboratory tests, lung CT imaging and prognosis, and analyzed the treatment plans of the two groups.

Small Host-Guest Systems in the Gas Phase: Tartaric Acid as a Host for both Anionic and Cationic Guests in the Atmospheric Pressure Chemical Ionization Source of Ion Mobility Spectrometry.

The ionization of tartaric acid (TA) in an atmospheric pressure chemical ionization corona discharge ion source was studied by ion mobility spectrometry (IMS) with zero air as the drift gas. Density functional theory was used for structural and thermodynamic analyses of the produced ionic clusters. Ion mobility spectra of TA were recorded in both positive and negative modes of CD with and without ammonia and chloroform as dopants in order to produce NH and Cl, respectively, as the reactant ions (RIs).

Hypnotherapy in management of delivery pain: a review.

Hypnosis in obstetrics is available for more than one hundred years, but the development of inhalational anesthetic and chemotherapy agents and anesthesia drugs pending the 19th century induced the decrement of its application. However, experimental assessment of this type of intervention on labor and delivery in not high yet. For this reason, evaluation of hypnotic techniques in preparing childbirth should be carried out.
