Integrative review of Islamic marketing

2021

Purpose The purpose of this study is to integrate and synthesize the Islamic marketing literature, understand the phenomenon and related concepts and provide suggestions for future research. Design/methodology/approach The study uses an integrative review method that emphasizes summarizing and synthesizing the previous literature related to a phenomenon. Findings The findings indicate the emergence of five major themes, namely, Islamic marketing and its perspectives, activities in Islamic marketing, opportunities, controversies and challenges in Islamic marketing, Islamic principles and determinants of consumers’ behavior and awareness toward Islamic products. Each of the major themes cons…

Available Lysine in Protein, Assay Using o-Phthalaldehyde/ N-Acetyl-L-cysteine Spectrophotometric Method

1992

An assay was based on reaction of free e-amino groups in proteins with the o-phthalaldehyde/N-acetyl-L-cysteine reagent to form isoindoles, which absorb at 335 nm. The procedure was suitable for proteins or mixtures of proteins with available lysine contents of more than 5 moles lysine/mole protein and required absence of free amino acids and peptides. This method was simpler and more convenient than other methods, since it did not require hydrolysis, amino acid analysis, long heating periods or solvent extraction.

Determination of total free amino acids with o-phthalaldehyde and N-acetyl-l-cysteine

1990

Abstract A spectrophotometric procedure is proposed for the determination of total free amino acids after reaction with o-phthalaldehyde and N-acetyl- l -cysteine, using isoleucine as the reference. The procedure was applied to the analysis of five samples of widely different composition. Recoveries were 98–105%.

SUNCT/SUNA in Pediatric Age: A Review of Pathophysiology and Therapeutic Options

2021

The International Classification of Headache Disorders, 3rd edition (ICHD3) defines Short-lasting Unilateral Neuralgiform Headache Attacks (SUNHA) as attacks of moderate or severe, strictly unilateral head pain lasting from seconds to minutes, occurring at least once a day and usually associated with prominent lacrimation and redness of the ipsilateral eye. Two subtypes of SUNHA are identified: Short-lasting Unilateral Neuralgiform headache attacks with Conjunctival injection and Tearing (SUNCT) and Short-lasting Unilateral Neuralgiform headache attacks with cranial Autonomic symptoms (SUNA). These pathologies are infrequent in children and difficult to diagnose. The authors reviewed the ex…

Functional evaluation of a “lingual ring” oral device applied on patients affected by temporo-mandibular disorders tmds: A comparative clinical trial

2021

This study aims to evaluate the functional variations of the electromyographic response and clinical symptomatology in TMD patients. This study has been performed and compared before and after the application of a therapeutic protocol based on the use of an oral device working on the proper mandibular repositioning through the proprioceptive-based lingual re-education called “Lingual Ring”. Between January to December 2016, 32 TMD patients have been recruited out of a series of 321 individuals recruited at the Neurosensorial and Motorial Surgery Department, in Palermo (Italy). All the patients underwent the Surface Electromyography (sEMG) of Masseter and Temporal muscles, with different reg…

Chronic paroxysmal hemicrania and hemicrania continua responding to topiramate: Two case reports

2007

Chronic paroxysmal hemicrania (CPH) is a rare primary headache syndrome, which is classified along with cluster headache and short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing as a trigeminal autonomic cephalalgia (TACs). Hemicrania continua (HC) was previously classified as one of the TACs, but in the recent second classification of the International Headache Society this disorder was moved to the group of other primary headaches. Both CPH and HC are characterised by moderate to excruciating pain requiring pharmacological treatment; furthermore, both conditions are characterised by an absolute response to indomethacin, which represents one of the…

HALAL gaļas ražošana un tās eksports no Latvijas

2019

Šī Muhamada Adnana (Muhammad Adnan) pētījuma mērķis ir konstatēt un novērtēt Halal pārtikas nozari, tās izaugsmi attīstītajās un jaunattīstības valstīs, kā arī noskaidrot iespējas, kā sabiedrībā popularizēt un veicināt Halal produktu izmantošanu uzturā. Pētījumā izmanto tās metodes balstītas uz uzņēmējdarbības vides novērtēšanu Halal pārtikas nozarē, tiešsaistes pētījumiem un dokumentu, zinātnisko rakstu analīzi. Konstatēts, ka, lai gan attīstītajās valstīs ir mazāk musulmaņu, Halal gaļas un pārtikas nozares tirgus daļa ir salīdzinoši augsta. Latvija ir valsts ar nelielu skaitu musulmaņu salīdzinājumā ar valstīm citviet pasaulē, bet tai ir stratēģiski laba atrašanās vieta, lai iegūtunozīmīg…

Use of pH gradients in continuous-flow systems and multivariate regression techniques applied to the determination of methionine and cysteine in phar…

1997

Abstract The simultaneous spectrophotometric determination of methionine and cysteine in presence of cystine and other compounds in pharmaceuticals, using a multivariate calibration method, was studied. The method is based on the reaction between the analytes and the o- phthalaldehyde -N- acetyl - l - cysteine (OPA-NAC) reagent performed in a continuous-flow system (FI). The FI system allows the generation of a local pH gradient in order to produce spectral and/or kinetic changes in the UV-Vis spectra of the amino acid-OPA-NAC derivatives. This information is used to improve the prediction ability of the Partial Least-Squares (PLS) models. The performance of two FI assemblies, the selection…

Spectrophotometric Determination of Cystine with O-Phthalaldehyde in the Absence of Thiol

1988

Abstract A spectrophotometric method for the determination of cystine with o-phthalaldehyde (OPA) in the absence of thiol is described. When cystine is heated at 60[ddot]C for 30 min in a low excess of OPA (pH 9.5), a very stable derivative with 1:2 stoichiometry (cystine:OPA) and an absorption maximum at 335 nm (E = 4600) is formed. At pH < 1 the derivative is protonated (protonation constants: log K1 = 5.88 and log K2 = 3.70 at I = 0.1 and 20[ddot]C) and another absorption band at 440 nm (E = 3800) appears, which allows the determination of cystine in the presence of other amino acids.
