BACKGROUND Clonidine, gabapentin, and promethazine are commonly used by people who use opioids, including heroin, raising concern for increased morbidity and mortality in a vulnerable population. We aimed to characterize how and why individuals use opioids in combination with these three psychoactive medications (PAMs). METHODS Participants (n = 103) were a convenience sample of adults attending a syringe service program who reported using a PAM in addition to opioids or opioid agonist therapies (buprenorphine or methadone). Face-to-face structured interviews consisted of closed and open-ended questions. RESULTS Patterns of PAM use varied. Risky use, including use of high doses and with other sedating medications, was common. Most individuals reported multiple medical reasons for use, even while reporting the PAM had mind-altering effects. Use of high doses of PAMs was associated with a history of overdose. Among those with a history of overdose, 32% reported that a PAM was involved. CONCLUSION The use of clonidine, gabapentin and promethazine among individuals who use opioids is complex. Providers should take individualized approaches to PAM prescribing, recognizing both the risks of PAMs and the potential unintended consequences of supply-side interventions in the era of the overdose crisis. Harm reduction interventions are needed to prevent PAM-involved overdoses. Despite the rapid increase of clinical and basic-science knowledge on ketogenic diet therapies over the past years, it has not always been easy to determine the adequate indications of this treatment. Over the nearly 100 years of use, from being a last resource in the therapeutic algorithm, the diet has become one of the four main treatments for patients with difficult-to-control epilepsy together with antiepileptic drugs, surgery, and vagus nerve stimulation. The use of the diet has also changed. The current paper will briefly discuss the history of the diet together with a review of the literature regarding its most important indications and how they have evolved. The concept of the importance of defining the type of seizure, type of syndrome, and etiology in the selection of patients and timing of diet initiation has been gaining importance. This paper explores how the indications of the diet changed together with the shifting focus of epilepsy teams towards its use in different types of epilepsy and epilepsy syndromes and according to etiologies and as an alternative option in refractory and superrefractory status epilepticus. Intramuscular fat (IMF) content is critical in the determination of eating quality. At present the Australian lamb industry has no ability to measure IMF as carcases are not split and processing speeds of up to 15 animals per minute prohibit the use of traditional methods. Consequently, the potential for a hand-held Near- Infrared (NIR) device to predict the IMF content of lamb topside in-situ was investigated. Models demonstrated that there is an ability to predict the IMF content of topside (R2 = 0.58, RMSEP = 0.85) using NIR spectra collected at 24 h post-mortem and loin (R2 = 0.50, RMSEP = 0.91). However, the models were limited by the range and distribution of the lamb population measured. Thus, further research is required to determine whether these models can be improved by increasing the range of data in the calibration models and considering alternate methods of analysis which are suitable for skewed populations. This paper aimed to investigate the dose-effects of l-Lysine (Lys, 0.2% to 0.8%) on the water holding capacity (WHC), textural properties, water mobility and distribution, microstructures and sensory acceptance of reconstructed ham with 50% reduction of added salt. Results showed that reducing salt from 2.50% to 1.25% caused significant increase in cooking loss and centrifuge loss, and decrease in hardness, springiness and chewiness. 0.8% Lys significantly improved the WHC and textural properties of salt-reduced hams, whereas 0.2% Lys further impaired these attributes. Moreover, 0.8% Lys improved the sensory scores for mouthfeel, appearance, taste and global acceptance. The NMR analysis reveals that water distribution and mobility were affected by salt reduction and Lys addition, and hams with 0.8% Lys contained more entrapped water with decreased mobility. Furthermore, a fine network with more bridge-linkage among myofibrils was formed in hams with 0.8% Lys. Therefore, addition of 0.8% Lys showed great potential in developing salt-reduced reconstructed ham with premium technological and sensory qualities. This study evaluated the effects of dietary rumen-protected betaine (RPB) supplementation on the fat deposition of lambs. Sixty Hu sheep were randomly divided into 5 groups. The lambs were fed a control diet (CON) or diets supplemented with 1.1 g/d unprotected betaine (UPB), 1.1 g/d RPB, 2.2 g/d RPB or 3.3 g/d RPB for 70 days. Compared with UPB, the abdominal fat in 2.2 g/d RPB supplemented group was decreased (P  less then  .05). selleckchem Compared with CON and UPB, the fat contents in longissimus dorsi (LD) of RPB treatments were increased (P  less then  .01). With increasing of RPB levels, the fat content in the LD was quadratically increased (P  less then  .05). Compared with CON, genes expression of PI3K, mTOR and S6K1 in the LD of RPB treatments were up-regulated (P  less then  .05). In conclusion, RPB supplementation decreased the abdominal fat in lambs but increased the fat content in lamb meat, and this effect might be regulated by mTOR signaling. The objective of this study was to compare the effects of two oxidation systems on the biochemical properties of yak myofibrillar protein (MP). Oxidation was induced by incubating MP with either an iron-catalyzed oxidizing system (IOS) or a metmyoglobin-oxidizing system (MOS). The following indicators of protein oxidation and protein degradation were analyzed. The carbonyl, disulfide bonds, dityrosine, and β-sheet content increased markedly with oxidant concentration in both systems(P  less then  .05), whereas the total sulfhydryl, surface hydrophobicity and α-helix content decreased significantly(P  less then  .05). Furthermore, the MOS carbonyl formation rate was significantly faster than the IOS rate, and the MOS significantly affected the formation of disulfide bonds and inhibited the exposure of hydrophobic amino acids. Both oxidative systems promoted cross-linking of myosin heavy chains (MHCs) and action, but the degree of cross-linking in IOS was greater than that in MOS. MOS also promoted cross-linking of myosin light chains (MLCs).
