This project contributes to the College's role in conducting research, and teaching research methods. You are under no obligation to reply to this email, however if you choose to, participation in this research is voluntary and you may withdraw at any time


Hello! We are looking for healthy adults with no personal or family history of mental health problems and people with bipolar disorder, aged 18-60, to take part in our research study.


> What is the study about?


Medications which block a type of brain chemical receptor, called the 5HT7 receptor, may be a promising new treatment for cognitive impairment experienced by people with bipolar disorder. 5HT7 antagonists. This study aims to examine how JNJ-18038683 might affect brain activity produced by cognition and mood tasks in both people with bipolar disorder and healthy adults. The effects of JNJ-18038683 will be investigated by giving participants a week-long dose of 20 mg of JNJ-18038683 or placebo capsule before a brain scan called a magnetic resonance imaging (MRI) scan. The participants will be asked to perform thinking and mood tasks whilst being scanned.


> What does participation in the study involve?


This study will include four visits to the Institute of Psychiatry, Psychology and Neuroscience, King's College London.


You will be asked to attend a screening session lasting approximately 2 hours to ensure that you are suitable to take part in the study. This visit will include some questions about your medical and mental health history, physical examination, blood sampling and some questionnaires about your personality. If you are eligible, the study will involve a further three visits. The next visit will be a Baseline visit lasting approximately 2.5 hours, where we will repeat the physical examination to ensure your health hasn?t changed and you?re still able to participate. Women of childbearing potential will also have a urine pregnancy test. Again, you will complete some questionnaires about your mood, and some tests of your memory, attention, and concentration with a researcher. At the end of this visit, you will be provided with the first week of study medication and a study diary. We will ask you to use the study diary to record that you have taken the medication and whether you experienced any side effects.


The next two visits will be imaging visits taking place on the seventh day of taking the study medications (JNJ-18038683 or placebo), each lasting about 4.5 hours. Again, we will do a brief physical examination, blood sampling and some questionnaires. On one visit you will receive JNJ-18038683 and on the other you will receive the placebo. You will then be asked to have an MRI scan which will last about 1 ? hours. While in the scanner you will be asked to complete some computer tasks designed to test your memory and emotional processing.


Following the scan, a doctor will carry out a brief physical examination and you will then go home as long as the study clinician has decided that it is safe for you to leave. Three weeks later, on day 7 of your second course of study medications, you will be invited to attend the centre again where we will ask you to complete the same procedures as in the previous scanning day visit.


> What could make you ineligible for the study?


The following reasons are likely to mean you can?t take part in the study:


- If you have, or have had, any serious medical or neurological condition.

- If you have a current, or past history of major psychiatric disorder (with exception of bipolar disorder for participants with bipolar disorder.

- If you are currently taking certain medications (please see list at the bottom of the page).

- If you are allergic to JNJ-18038683 or other medications with 5HT7 antagonist properties such as lurasidone (Latuda) or vortioxetine (Trintellix).

- If you have taken part in a research study involving administration of an experimental drug within the last 3 months or plan to do so up to two weeks after the study.

- If you take recreational drugs.

- If you have any metallic or electronic objects in your body, e.g. pacemaker, cochlear ear implants, fixed dental braces.

- If you are claustrophobic or cannot lie still in an MRI scanner for a period of around 1 ? hours.


For women: if you are currently not using an effective contraceptive method, plan to get pregnant in the next three months, or if you are currently pregnant or breast feeding.


For people with bipolar disorder: if there is likely to be a change in dose or type of your regularly prescribed mental health medications the month before the screening visit or a likely change during your participation in the study


> Will you be compensated for your time?


You will be paid ?200 to compensate you for your time if you complete the study. We will also reimburse reasonable travel expenses and provide you with lunch during the scanning sessions.

    • But all those examples sell a wide variety of things,  and mostly they are well spread out along Lordship Lane. These two shops both sell one very specific thing, albeit in different flavours, and are just across the road from each other. I don't think you can compare the distribution of shops in Roman times to the distribution of shops in Lordship Lane in the twenty first century. Well, you can, but it doesn't feel very appropriate. Haa anybody asked the first shop how they feel? Are they happy about the "healthy competition" ?
    • ED is included in the 17 August closure set (or just possibly 15 August, depending on which part of the page you trust more) listed at https://metro.co.uk/2025/07/25/full-list-25-poundland-stores-confirmed-close-august-23753048/. Here incidentally are some snippets from their annual reports, at https://find-and-update.company-information.service.gov.uk/company/02495645/filing-history. 2022: " during the period we opened 41 stores and closed 43 loss-making/under-performing stores.  At the period-end we were trading from 821 stores in the UK, IoM and ROI. ... "We renogotiated 82 leases in the year, saving on average 45% versus the prior lease agreement..." 2023: "We also continued to improve our market footprint through sourcing better store locations, opening 53 and closing 51 stores during the year." 2024:  "The ex-Wilco stores acquired in the prior year have formed a core part of this strategy to expand our store network.  We favour quality over quantity and during the period we opened 84 stores and closed 71 loss-making/under-performing ones."
    • Ha! After I posted this, I thought of lots more examples. Screwfix and the hardware store? Mrs Robinson and Jumping Bean? Chemists, plant shops, hairdressers...  the list goes on... it's good to have healthy competition  Ooooh! Two cheese shops
