PSMA was highly expressed in the vascular endothelium of grade IV gliomas and BM, while its expression was extremely low in LGG and completely absent in gliosis. By using 2.8 as a threshold value for TBRmax, the specificity, sensitivity, PPV, NPV and accuracy were 100%, 94%, 100%, 77% and 95%, respectively.

The results of this pilot study show that [

Tc]Tc-iPSMA SPECT brain imaging is a specific and potentially useful neuroimaging tool for assessing tumoral neovasculature formation in gliomas and brain metastases.

The interpeduncular nucleus (>1840) (IPN) has been shown to modulate the behavioral effects of nicotine withdrawal in male rodents. To date, the contribution of this brain structure to sex differences in withdrawal is largely unexplored.

This study compared neuronal activation, as reported by observable Fos expression in the IPN of nicotine-dependent female and male rats experiencing withdrawal. We provisionally localized the Fos-expressing cells to certain IPN subnuclei within Swanson's standardized brain atlas (2018). Adult female and male rats were prepared with a pump that delivered nicotine (3.2 mg/kg/day; base) continuously. Controls received a sham surgery. Fourteen days later, the rats received administration of saline or the nicotinic receptor antagonist, mecamylamine (3.0 mg/kg; salt), and physical signs and anxiety-like behavior were assessed. The rats were then euthanized and brain sections containing the IPN were processed for Fos immunofluorescence to infer the possible IPN subnuclei displaying differential activation between sexes.

Both female and male rats displayed withdrawal-induced Fos expression within the IPN. Compared to males, female rats displayed greater numbers of withdrawal-induced Fos-positive cells within a circumscribed portion of the IPN that may fall within the cytoarchitectural boundaries of the central subnucleus (>1840) (IPNc). The withdrawal-induced activation of the IPN was correlated with negative affective states in females, but not males.

These data suggest that a centrally located group of IPN cells, presumably situated partly or completely within the IPNc, play a role in modulating sex differences in negative affective states produced by withdrawal.

Despite effective, evidence-based medications for opioid use disorder (MOUD), these treatments remain underutilized. This may be due to multiple reasons. Family members may impact patient decision-making when choosing an opioid use disorder (OUD) treatment. Bromodeoxyuridine research buy While there has been work on patient preferences and attitudes towards opioid use disorder (OUD) treatment, to date, there has been minimal work assessing the attitudes of family member towards OUD treatment and recovery.

Participants were ≥ 18 years of age and endorsed having a first-degree family member with past-year treatment for OUD. Participants were recruited via online crowdsourcing and were asked a number of questions regarding their desired outcomes for OUD treatment, and their familiarity, approval, and perceived effectiveness of various OUD treatment options.

The most commonly reported desired treatment outcome (50 %) was for family members to never use any kind of opioid, including maintenance therapies or opioid analgesics. Mean familiarity ratings for MOUD (rated 0-100) were relatively low, with naltrexone being the least familiar (32.3). Among those who endorsed a familiarity rating of at least 30 for a given treatment, mean approval and effectiveness ratings were relatively low-buprenorphine (approve 55.1; effective 54.1), methadone (approve 51.9; effective 49.3), naltrexone (approve 61.6; effective 55.9). These were lower than approval and effectiveness ratings for all non-MOUD treatments queried.

These findings highlight a need for clinicians and researchers to engage with family members' regarding their preferences and understanding of treatment, and to better understand how this might impact patient engagement with treatment.

Daily use of marijuana is rising in adolescents, along with consumption of high potency marijuana products (high % Δ-9-tetrahydrocannabinol or THC). These dual, related trends have opened gaps in understanding the long-term effects of daily consumption of a high dose of THC in adolescents and whether a therapeutic dose of cannabidiol (CBD) modulates THC effects.

Adolescent squirrel monkeys (Saimiri boliviensis) were treated daily for four months with vehicle (n = 4), a high THC dose (1 mg/kg i.m.; n = 4), or THC + CBD (1 mg/kg +3 mg/kg i.m.; n = 4), to investigate whether (1) a daily high THC dose affects performance in tasks of cognition (repeated acquisition, discrimination reversal); (2) a daily high THC dose affects spontaneous behavior and day/night activity (3) tolerance develops to the behavioral effects of THC; (4) whether CBD modulates THC effects.

THC impaired performance of adolescent monkeys in a cognitive test initially, but not performance on a task of cognitive flexibility. THC reduced motor activity and increased sedentary behavior, with tolerance developing after weeks of daily treatment. Co-administered with THC, CBD did not modulate THC effects on cognitive performance, activity or tolerance, but prevented THC-induced emesis on the first day of daily treatment.

Daily high dosing with THC compromised performance on a task of cognition, and reduced activity in adolescent primates, with tolerance developing within weeks. Whether our observations are relevant to a broader range of cognitive tasks vital for daily function in human adolescents is uncertain.
