Heroin

Heroin is a highly addictive opioid drug derived from the morphine found in the opium poppy plant.
It is used illicitly to produce a potent 'high' characterized by euphoria, sedation, and respiratory depression.
Heroin can be injected, snorted, or smoked, and its use carries significant health risks including overdose, dependence, and increased susceptibility to infectious diseases.
Reserach into effective treatment and prevention strategies for heroin addiction is an important public health priority.

Interviews were conducted by trained research staff in a private setting and data were recorded anonymously, unaccompanied by any unique identifiers. Subjects were first asked the single screening question, “How many times in the past year have you used an illegal drug or used a prescription medication for non-medical reasons?” (where a response of ≥1 is considered positive). If asked to clarify the meaning of “non-medical reasons”, the research associate added "for instance because of the experience or feeling it caused”. After subjects responded to the single screening question, they were asked if they had ever experienced any of a list of problems related to drug use. For this we modified the previously described Short Inventory of Problems-Alcohol and Drug (SIP-AD) questionnaire, which asks about problems ever experienced in the subject’s lifetime related to alcohol or drug use8 (link). We modified this by eliminating the word alcohol from the questions, a modification we hereafter refer to as the Short Inventory of Problems- Drug Use (SIP-DU). In a separate analysis (but in these subjects) we determined the reliability and validity of the SIP-DU as a measure of drug use consequences 9 . The computerized version of the Composite International Diagnostic Interview (CIDI) Substance Abuse Module was used for the assessment of current (12-month) drug use disorders 10 . This structured interview yields a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnosis of drug abuse or dependence. In addition, as part of the CIDI, subjects were asked detailed questions about current (past year) use of illicit drugs (marijuana, cocaine, heroin, stimulants or hallucinogens) and non-medical use of prescription drugs. Following the interview subjects were asked to undergo oral fluid testing for the presence of common drugs of abuse (opiates, benzodiazepines, cocaine, methamphetamines, tetrahydrocannabinol (THC). Once collected, oral fluid was sent to an outside laboratory for analysis using methodology that yields results comparable to urine drug screening (Intercept™ immunoassay, OraSure Technologies, Bethlehem, PA)11 (link)–14 (link). In order to aid in the interpretation of drug test results subjects had been asked, as part of the interview, if they had recently been prescribed any drugs from a list of opiates or benzodiazepines. Because this question was added to the questionnaire during the study, responses were missing from 23 subjects who underwent oral fluid testing. Subjects were not told that they would be asked to undergo drug testing until the interview was complete. After completing the interview, they were compensated and thanked for their participation. They were then asked to undergo oral fluid testing and a second informed consent process was completed. Following the single drug screening question, but before the other assessments, the 10-item Drug Abuse Screening Test (DAST-10) was administered for comparison 4 (link). As part of a parallel study on screening for unhealthy alcohol use, subjects were also asked a single alcohol screening question (preceding the drug screening question), two other brief alcohol screening questionnaires and a calendar based assessment of past-month alcohol consumption (all after the drug screen and prior to the CIDI) 7 (link).

We processed the EMPIAR-10234 clustered protocadherin dataset in two separate ways to test whether picking in denoised micrographs was advantageous: First by using the particle picks provided by the data owner, and second by manually picking on the denoised micrographs.
The picking method used by the data owner is described in Brasch et al.25 (link) Briefly, 1540 particles were manually picked by the data owner from 87 raw micrographs and used to train a Topaz16 picking model, resulting in 14,569 particles. The following reconstruction workflow was performed in CryoSPARC v218 (link) using C1 symmetry in every step and using frame-summed particles for consistency. 2D classification was performed three times to remove obvious non-particle classes, resulting in 13,739 particles. Ab initio reconstruction with two classes was performed, resulting in one good class with 10,010 particles. 3D homogeneous refinement using “gold standard” FSC was performed resulting in the final reconstruction.
The picking method we used is as follows: frame-summed micrographs were denoised with the Topaz-Denoise v0.2.1 L2 model, proprocessed with “topaz preprocess” while binning by a factor of 4, and 1023 particles were manually picked not by the data owner from 215 denoised micrographs. A Topaz16 picking model was trained using the particle coordinates on raw micrographs, resulting in 59,273 particles. The following reconstruction workflow was performed in CryoSPARC v2 using C1 symmetry in every step and using frame-summed particles for consistency. 2D classification was performed three times to remove obvious non-particle classes, resulting in 44,303 particles. Ab-initio reconstruction with two classes was performed, resulting in one good class with 23,695 particles. Heterogeneous refinement with 2 classes was performed, resulting in two classes with different conformations. 2D classification and heterogeneous refinement with these two classes and a junk class were performed, resulting in 13,392 particles in the closed conformation and 8134 particles in the partially open conformation. 3D homogeneous refinement using “gold standard” FSC was performed on each class, resulting in the final reconstructions. UCSF Chimera40 (link) was used to render the final reconstructions.

As one of the most popular international destinations for backpackers from the UK[23 ,28 ], Australia was chosen as the country in which to conduct the survey. A cross sectional cohort study design was chosen which utilised a single questionnaire to measure individuals' backpacking experience (e.g. length of trip, destinations visited), behaviour in Australia and, for within individual comparisons, their behaviour in the UK prior to their trip[29 (link)]. Questions addressed alcohol, tobacco, illicit drug use and sexual behaviour and had been previously validated and utilised in studies of short holidays within Europe[2 (link),3 (link)]. However, some questions were adapted to examine the longer lengths of stay routinely experienced by backpackers in Australia and to include substances more commonly used in that country (e.g. methamphetamine[30 (link)]). Consequently, the range of illicit drugs examined included cannabis, ecstasy, amphetamine (i.e. amphetamine sulphate), methamphetamine, crystal meth or ice (methamphetamine in crystalline form), cocaine, crack, lysergic acid diethylamide (LSD), ketamine, gammahydroxybutrate (GHB), heroin and steroids.
Given the diversity of nightlife and other tourist environments in Australia, two contrasting locations were identified in which to sample backpackers. The first, Sydney (population approximately 4.2 million[31 ]), is a major international metropolis with a flourishing nightlife, busy international transport connections and consequently often the point of arrival and departure for backpackers visiting the country[21 ]. In contrast, around 2700 kilometres north is Cairns (population approximately 120,000[31 ]); the third most common tourist destination in the country after Sydney and Brisbane. Popular with overseas tourists and particularly international backpackers, the city has a less well developed nightlife but one that is very much designed for young travellers.
Ethics approval was received from the University of New South Wales Human Ethics Committee, the auspicing body for the study, and research methods complied with the Helsinki Declaration. Questionnaires were administered in Sydney (28th April–22nd November 2005) and Cairns (1st–6th August 2005). In both locations backpacking hostels were utilised as the sites for sampling potential respondents and within each hostel researchers approached individuals on a convenience basis. Inclusion criteria for the survey were being age 18 to 35 years, having already been in Australia for at least two weeks and being a UK national. In all cases researchers explained to potential respondents the content of the survey and its anonymous nature. Informed consent was recorded and participants were reimbursed $AUS10 for their time. All individuals meeting the inclusion criteria and agreeing to participate (n = 1012 of 1114 approached; participation rate 90.8%) were given a questionnaire, pen and plain envelope in which to seal the completed questionnaire and return it to the researcher. Completed questionnaires were entered into SPSS (Statistical Package for Social Sciences) for analysis[32 ]. At this stage a further four questionnaires were excluded as responses did not meet survey inclusion criteria for age or period of stay (n = 3) and one questionnaire was spoilt (i.e. no effort had been made to complete questions and the questionnaire had been defaced).
Analysis utilised a combination of Chi Square, Mann Whitney U, McNemar and Wilcoxon signed rank tests with logistic regression being used to control for confounding relationships between variables when examining predictors of drug use. For logistic regression analyses, amphetamine, methamphetamine and crystal meth were combined into a single category of "used amphetamine type", and a category of "used any illicit drug" was also created.

Women leaving home or becoming homeless at an early age were particularly vulnerable to predatory relationships with older men or romantic relationships of necessity and convenience. Prior studies found a particular association between intimate relationships as a source of increased violence and transitions into injection drug among females [67 (link)]. Consistent with these findings the women in this study frequently described how partners introduced them to drugs and were the catalyst to transition into “harder” drugs:

met a guy who was like 29 and he gave me heroin, like I’d never touched drugs in my life, he injected me, with heroin. I know. I had crack. I didn’t really know what I was taking. He introduced me to heroin at 15 (Gillian).

Intimate relationships were often based on the need for protection: “[partner’s name] is there all the time cos she protects us. She makes us like get up in the mornings and try and get ready and get washed, and stuff like that and she’ll like cooks for us and like she is there. If she hadn’t have been, I wouldn’t be here” (Carina).
Several women met their partners through drug networks and were subsequently coerced into drug dealing: [I met him] through different people in […], who were selling drugs and people knowing people and me being young he swept us off my feet, wined and dined us and I was a lot younger and – he used us basically, to his advantage. “Well if you do this, do that, I’ve got me third strike I’m out, you’ll have to sell this and that” (Delia).
Gillian illustrates the difficulty of getting away from the pull of street culture. Having had a relatively happy and stable relationship for several years, coinciding with better mental health, a job and sense of purpose, the end of that relationship swiftly led to her going back to where she felt a “connection”, a drug dealer who knew her which she associated with having a sense of belonging:

When I was with [partner] and we were both PT [Personal Trainers] everything was fine … my life was absolutely the best … No domestic violence or nothing. I was just happy … I was drug free, like totally, just normal just normal shit and he broke my heart and that and I ended up, like not back on heroin just crack. I started using cocaine and drinking and that you know, cos he left us. And then from then I went out like a coke dealer who I knew from all them years ago when I had [...] who used to serve us up. And I felt like a connection with him cos he knew us (Gillian).

Intimate relationships were entered into out of necessity, following crisis points (homelessness, death of previous partner) and women described partners exacerbating drug use, or precipitating further trauma and abuse.

Repeated experiences of domestic abuse were apparent in the biographies of almost all women though it was not always perceived as such. Relationships were often idealised in the first few months then quickly descended into abuse:

You think you find the right person, you think they’re so nice and everything’s perfect for the first 6 to 12 months and then after 12 months it just goes pfffft. Like woah. And by the time that’s happened you’re just too far involved. And then you end up the one that’s out on the street (Rosa).

One of the most harmful aspects of domestic abuse is detachment from social networks, thus further deepening exclusion. Here, Sally describes being isolated her from family and friends and eventually her children: Nobody knew what was going on. So I eventually left, and unknown to me … I was made out to be the bad person, like a complete weirdo (Sally).
Several women described long term physical and mental health impact resulting from injuries caused by their partner. Dee was using heroin to manage chronic pain caused by physical injuries as well as trauma from abuse: “I was married once. And I’d never do it again. He was a woman batterer. Steel plate in my head. He was so violent” (Dee).
Other women described how their partner provided resources but also perpetuated further trauma:

he used to say “you’ve got nobody. You’ll never go hungry if you stay with me...” And it’s just hard like. I struggle every day. So it’s like I’m either, it’s easier for food, I’d get lifts if I needed to go to places or I’m not being with that person and struggle. Erm, but not arguing and not fighting. It’s just hard (Sienna).

Michelle describes how her relationship commands a lot of her attention and energy, with expressions of affection interspersed with mental turmoil and uncertainty:

Me partner who lives with me, [name], he’s really well known here. He got kicked out of a hostel a while ago and that’s how I met him... he’s playing us [me] along saying he loves me and wants to be with me, and it’s ripping me to bits, my heads battered. … he doesn’t have a good word for us. Constantly puts us down. I don’t know. But he walked away a couple of month ago when he got paid, spent £750 left me with not a penny and went away for a week and come back when he had nothing. I knew then, he didn’t love me. No-one who loved someone would do that to them. You know. I couldn’t see the lad on the streets, I just couldn’t (Michelle).

Amongst the women who had exited homelessness, many chose to live alone: “I mean I just don’t intend getting into a relationship to discover how to have one. I’m done. I’ve had enough bad ones. I’ve loved, and I’ve been loved back a couple of times. But it hurts even harder when they’re the ones that try to kill you” (Tracy).
Most of the women who had successfully exited homelessness actively avoided situations where they might meet a new partner and expressed no desire for intimate relationships. This perhaps relates to not only their overwhelmingly bad experiences of relationships, but provides context to their perception of relationships primarily driven by necessity to obtain shelter, protection and resources.

A gold-bearing cable was obtained from the local electronic junk shop. The yellow cable (15 mg) was first leached with a mixture of HBr and H2O2 overnight. Subsequently, the acid concentration in the HAuBr4-containing leaching solution was adjusted to 1 M with ultra-pure H2O, and the insoluble impurities were removed by filtration. A saturated aqueous solution of β-CD containing ∼1 M HBr was added to the leaching solution, forming the HAuBr4⊂β-CD complex. Upon adding 0.1% (v/v) of DBC, the solution became gradually cloudy. After stirring for 5 min, the co-precipitate of HAuBr4·DBC⊂2β-CD was separated from other metals by filtration and washed with ultra-pure H2O. The metals trapped in the co-precipitates were analyzed by ICP-MS by comparing them with the metal concentrations of the solution before and after adding DBC. In order to convert the [AuBr4] anions trapped in the co-precipitate to gold metal, the HAuBr4·DBC⊂2β-CD co-precipitates were dispersed in an aqueous solution and reduced with N2H4·H2O. After centrifugation and washing with H2O to dissolve the residual β-CD, gold metal was obtained. β-CD, which dissolves in the aqueous solution, can be recycled by precipitating with acetone and followed by recrystallization.

We provided a total of eight nutrition education sessions at intervention schools for two months. An hour-long nutrition education session (60 minutes to 80 minutes long) was provided among the girls of each grade once in a week by the trained female staffs who received training on how to impart nutrition education among adolescent girls, from the investigators of the study. They consulted with headmasters and teachers at the schools to set the convenient time for providing education sessions. Nutrition education sessions were delivered using audio-visual techniques (audio-visual presentation). The components of eight education sessions have been described in detail in “Table 1”.
These 8 nutrition education sessions were made based on Food and Agricultural Organization (FAO) recommended dietary diversity chart representing 16 food groups [27 ]. The First session included “Food group 1” which represented “Cereals”, the second session was about “Food group 2” representing “White roots and tubers”, the third session included “Food groups 3, 4, 5, 6, 7” which were about “Fruits and Vegetables”, the fourth session was consisted of “Food group 8, 9, 10, 11” presenting “Animal protein”, the fifth session was about “Food group 12” presenting “Plant protein”, the sixth session included “Food group 13 and 14” which represented “Milk and milk products”, seventh session was about “Food group 15” presenting “Sweets” and eighth session were about “Home-made food” incorporating the importance of consuming home-made food and health hazards of taking junk foods. In every session, a detailed description of each food group was given by showing pictures of the locally available Bangladeshi food items of that food group to the students through power-point presentation. The health benefits of taking those 16 diversified food groups and health problems in absence of those food groups in daily meals were also explained. We conducted recap sessions and quiz in every week before starting the next session for evaluating whether the girls were learning effectively. Our intervention was to inform them about 16 diversified food groups in detail along with their health benefits, health problems in absence of those food groups in daily meals, proper timing as well as the frequency of taking meals in 24 hours, and how to select diversified meal at low cost.
